The Garmin Forerunner 735XT is the latest exponent of Garmin for the multisport range, i.e. for triathlon, duathlon, aquathlon and other activities ending in "lón". In short, a watch that allows you to record an activity composed of several separate sports (e.g. swimming and running).
After several weeks of use with the unit provided by Garmin I am now able to tell you the best and the worst of this new version of the Forerunner range. Once the test is over, I will send it back. There is no compensation from the brands for the tests I perform, so it is up to you to help maintain the site. How? If you like the test and it helps you to decide your purchase, do it through the links I provide. This way I will receive a small commission for each purchase (either of the 735XT or any other item you need), without any extra cost from you.
And now that that's all cleared up, it's time to start talking about the 735XT.
- Small and light
- Compatible with many sensors, including lights and power meters
- FTP calculation (with power meter)
- Highly configurable
- Good performance in open water swimming
- No altimeter
Garmin Forerunner 735XT
The presentation of the Garmin Forerunner 735XT changes a bit from that of its Forerunner brothers (230, 235 and 630). Instead of having the watch visible behind a plastic cover, it has a cardboard cover with much more presence.
Depending on the pack you buy (with or without sensor or pulse sensors), the size of the box will be one or the other. In this particular case, Garmin has sent me the Forerunner 735XT with Tri pack, that is, it includes the sensors Garmin HRM-Tri and Garmin HRM-SwimThere are two other options, the Run pack with an HRM-Run2 sensor or buy the watch without sensors of any kind, using only the integrated optical pulse sensor or the sensors you already have from previous models.
Comparing the box with the Garmin Forerunner 230 (on the right) you can see that it's quite a bit bulkier.
Once the front of the box is removed, the design is similar to the rest of the Forerunner range. Garmin gives the 735XT a premium touch by adding that extra front carton.
But let's go to the content. As it is the Tri pack, the two sensors mentioned above are included, and together with the sensors their corresponding extenders, which depending on the case you will have to use one or the other (more information about this in the HRM-Tri and HRM-Swim test).
As for the clock, aesthetically it is already an old acquaintance, because it shares a box (not the packaging, but the shape of the clock itself) with the 230, 235 and 630. Although the screen seems slightly larger, it is more an optical effect of a slightly narrower frame. When it comes to the real time the visible diameter is the same (31.1mm) and the resolution is also identical, with 215×180 pixels. It is a small improvement over the Foreunner 920XTThe camera has a slightly lower resolution (205×148 pixels).
There are no buttons on top of the watch, which are so convenient on the bike. Instead we have five buttons, three on the left side and two on the right. The functions are the same as usual for each of them, to turn the watch or the lighting on/off or to scroll through menus or different screens.
As always, the button to start or stop the activity is larger and different colored, to stand out as the main button, and we still have a button to mark the laps manually.
That is, the usual Garmin operation.
The material is plastic, both in the case and in the display. It makes the watch very light (only 44 grams), but it is true that it gives it a cheap watch look, quite in contrast when compared to other similar watches, both in price and target audience (Ambit3, V800, Fenix 3...). It is true that the 920XT also had this "problem", so it is not something that is remarkable.
On the back you find the Garmin Elevate optical pulse sensorSince it was introduced a few months ago in the bracelet Garmin Vivosmart HR And it will eventually become a basic feature of any Garmin model, as it is present in almost all of the sports watch range in one form or another.
The timing and charging cable is similar to the rest of the Forerunner range (230/235 and 630), and it could not be otherwise if the box has the same design.
Although the cable has been relegated to being used exclusively for charging the watch, few are left who do not sync wirelessly via their mobile phone. However, the current top of the Forerunner range has lost WiFi connectivity, although I think this is not a major loss as it is a fairly minor syncing option compared to syncing via Bluetooth Smart.
As you can see, the placement of the loading clip is similar to the other models.
Easy to place and maintain the connection correctly, although not as good as the Fenix 3 that leaves the clock anchored in the four corners. But we better put the clock in place and start moving a little with it.
Running with the 735XT
Of all the things the Garmin Forerunner 735XT has to offer, the racing part has the fewest surprises - in fact, there aren't any at all - because the 735XT has the same racing profile as the 630. So for those of you who were pining for a Forerunner 630 with an optical pulse sensor, here it is (without the touch screen, which nobody wants in the end), along with more sports modes.
As with the 630, it is possible to display up to 4 data per screen, and you have 4 screens on which you can configure the information as you prefer.
Next to these screens you can activate other independent screens: indicator of heart rate zone, mapThe virtual partner, two different screens of career dynamic and another screen with the time. Here you can see those screens (except the one with the time, because you know how it is).
Most of the additional screens allow for adjustments such as selecting the main metric on each race dynamics screen, the virtual partner target pace or map orientation.
And while we're on the subject of racing dynamics, I'd like to remind you that you'll need to wear your chest pulse sensor to get this data. Even though Forerunner 735XT has the integrated heart rate monitorIn the case of the HRM-Run sensor, the advanced dynamics data comes from the accelerometers that have the HRM-Run sensors (in either version) or HRM-TriSo if you buy the watch without any associated sensor, you will not have this data.
You will have cadence data, but not the other metrics: vertical oscillation, ground contact time, stride length, vertical oscillation ratio and ground contact balance.
If you wear the sensor, you can get graphs like this after synchronizing your training.
What can you do with each of these data? You can see the article on how to interpret Garmin Connect data where I talk about it.
There is another series of possible configurations in the activity profile, both in the race profile and the other sports profiles I will talk about later, that is, each sports profile has its specific configuration and each change you make to it will only affect that profile.
So, because the 735XT allows you to add new sports profiles (not just the ones that come standard on the 230/235), you could have one race training profile and a different one for racing, with specific data screen and alert settings or other options.
All other common options remain unchanged: alerts, manual or automatic (editable distance) lap pause and automatic screen change, GPS with GLONASS activated, etc. And as in the higher range models, the metronome option for the cadence exercises.
I don't want to be repetitive, but I'll say it again. The benefits in terms of additional information are the same as those present in the Forerunner 630. Firstly, and as one of the newest additions (in fact it was launched with the 630) the calculation of the lactate threshold. The watch allows you to calculate through a guided test (or leave it in automatic mode so that as you accumulate different types of workouts it can do the calculation) which is your lactate threshold. That is to say, from what speed and pulse rate the watch estimates that you start accumulating fatigue.
Once the test is completed, or as I say, automatically, you will have an estimate of where your lactate threshold is, or the cut-off point between aerobic and anaerobic training.
Once the data is obtained, the watch allows you to update your heart rate zones automatically from these new values.
To do the test (or to obtain data automatically in the following training sessions) you need to have a pulse sensor paired. It is not possible to do the calculation only with the data from the optical sensor, because the algorithm requires pulse variability data, something that optical sensors cannot provide.
Remember, it is an algorithm that compares your data with a huge database of other athletes. The result will not be 100% true, but in many cases it is very close to an accurate data. If for example it indicates that your threshold is at 167 beats it may not be that exact, but I doubt that there is more than 5 beats difference with the real data.
We still have available the option of estimating Running VO2Max Although there will be no significant changes (once a record is reached it remains fairly stable, as the maximum volume of oxygen is influenced by one's own genetics), you may notice differences at some points, especially when there are changes in training load, when going from the end of the season to pre-season and to peaks for particular races.
When you start using it the value will be quite variable, because it has to get to know you. It will go up gradually (in fact, in other watches I have a value of 54) and once your maximum oxygen consumption point is reached, it will remain quite unchanged unless there are major changes in your training.
This VO2Max record also provides another piece of information, again compared to a database of different athletes, in which it provides you with a forecast of possible times for different distances.
You don't have to take it literally or count on those times for all distances; especially if you're not training it. Right now I'm not doing a preparation that would allow me to face a marathon, as if I wanted to do it in a little more than 3 hours...
Finally, the watch will keep a recovery time. Depending on the strength of each training session, it will recommend a recovery time. This does not mean that you cannot train until that timer reaches zero, but that it is not advisable to go back to high-intensity training. This means that if you do a series training session and it gives you 48 hours of recovery time, it is advisable not to go back to a similar intensity training session for two days (something you already knew, it is another thing to listen to it).
Also, when you start a workout, you will have a message after the first few minutes of the workout showing a scale with your recovery status (for now I leave you a picture of the 630 until I remember to take a picture of the 735XT 🙂 ).
In my case, the sensations perceived while training coincide with the data on the graph. If I see a -5 I know it will be a hard day, because I will have trouble doing what I have in the training plan. However, seeing a +8 on the screen does nothing more than confirm that I will indeed fly in the series that are scheduled that day.
When it comes to training, we still have the advanced trainer's. This is nothing new, as it's been in the Forerunner range for a few years now (even in the mid-range). You can create a workout with the different steps you need to perform and synchronise them to the clock so that when you go to train, you'll be reminded of the trainer's punishment for that day and whether you're meeting your goal.
But it's not the only way you can train - you can set up interval sessions quickly (though without setting pace or heart rate targets, just interval periods), set a distance, distance and time or distance and pace target (essentially a virtual partner), or compete against an activity you've already done, in an attempt to improve your time.
What about cycling? Well, I could repeat almost point by point what you just read in the previous section. And that is that the behavior of the cycling profile is very similar to that of racing. The main variation is that instead of recording a rhythm, you will do it in speed (usually in km/h, unless you prefer miles). The rest of the data screen configurations, alerts, GPS settings and so on are identical.
Where there is variation is in the time of the sensors that we can connect (or use). If in racing we can only use an external pulse sensor, footpod and some other external accessory (at the moment Garmin still does not give support to the power meters in racing), the options in cycling are multiplied. You can have the clock paired with a multitude of sensors, both of different metrics and of the Varia cycling range. In summary, these are the sensors from which you can receive information in the clock:
- External heart rate sensor
- Speed and/or cadence sensor
- Power Meter
- ANT+ lights (like those offered by Bontrager)
- Garmin Varia Lights
- Garmin Varia Radar
- External display Varia Vision (which can also be used in racing, although I do not recommend it)
- Shimano Di2 electronic switch (and probably SRAM Red eTAP in the future, as well as Edge 520 and Edge 1000 units)
- Garmin Tempe external temperature sensor (of course, it is also possible to use it in running or other profile)
- Garmin Virb action camera control (again, perfectly controllable on any other sports profile)
All these accessories will be connected through ANT+Even if the watch has connectivity Bluetooth You can only use it to connect to your smartphone, but not to Bluetooth power meters or Bluetooth pulse sensors, so if you have a Polar sensor, you can't use it with Forerunner 735XT (or any other Garmin).
There is currently a problem with the use of some sensors, something that has never happened to me with any other clock, so it must be a mere firmware failure that Garmin will have to fix in the next update. Sometimes the clock does not connect to the sensors automatically, and you have to enter the options menu to make the connection manually.
In training this can be a bit of a headache as you have to waste a minute of your life doing something that the clock should do fully automatically. But in racing it is crucial.
Coming from swimming to ride and realizing that you don't have power data can be crucial, especially if you're fighting for positions. Because you have two options: losing a few seconds to manually connect the sensor or having to race without power data (or cadence or whatever). And it's not just about the power.
Also with the other sensors, such as Various RadarAnd speaking of radar, Forerunner 735XT is the first Garmin watch to be compatible (the first to announce compatibility was the Vivoactive HRbut came on the market without including the option, receiving it later through a software update).
Pairing the sensor with the Varia radar gives you data on the traffic behind you, just like on the Edge. The clock beeps and vibrates to alert you of approaching vehicles. The screen will also display a dot for each of these approaching vehicles, and the colour of the sidebar will indicate the speed at which you are approaching, usually in orange and turning red if the speed difference is very high.
Going green when there are no more cars approaching and the road has been left totally free for us to drive.
This green strip disappears after you are notified that you are safe, leaving only the icon at the top indicating that you are connected to a light unit.
Finally, if in racing you have the lactate threshold calculation available, in cycling it will be the functional threshold power (commonly known as FTP), which is one of the main new metrics of the 735XT.
In the same way, you can obtain the automatic calculation with the different trainings you are doing or with a guided test, but for the guided test as well as for the automatic recognition it is necessary that the watch is paired with both a power meter and an external pulse sensor (the optical pulse sensor is not enough, as the lactate threshold requires pulse variability data).
As you can see, the 735XT is a device that acts as a cyclo-computer in almost the same way as an Edge unit. Garmin has done a fantastic job and continues to add new features to their triathlon watch to make training even easier. But I find two major problems.
Firstly, the absence of a barometric altimeter; there is something available on the 920XT that it is intended to replace or on the Fenix 3. Inexplicably, the 735XT does not have one, but there is a specific section for this purpose. Secondly, the absence, for the moment, of a quick mounting kit.
Both the 920XT and the Fenix 3 have it (as long as it's not the Fenix 3 HR). This accessory allows you to quickly move the watch from the wrist strap to the handlebar of the bike (and vice versa), with a simple quarter turn. It's tremendously useful in a triathlon competition where you want to be able to see the data without having to turn your wrist to see the watch (especially if you're attached to the handlebar). Garmin doesn't offer this accessory for the 735XT at the moment, and it's not clear if they plan to offer it in the near future either.
In the Garmin 735XTAs with many other multisports (or duathlon-triathlon) watches, we have two swimming modes available: in swimming pool or in open watersIn the first case it will use the internal accelerometer to count lengths (and therefore distance) and in the second case it is the GPS that will measure the distance. I will start with the first one.
Swimming in a pool
Before we start talking about strokes and lengths, I would like to remind you that the 735XT is compatible with the specific swimming sensors HRM-Tri and HRM-Swim. If you don't know them, I recommend you take a look at the proof of bothWhen you go to buy the watch, it is important that you know which pack you are interested in.
Once the subject of sensors is out of the way (it's quite a long thing to deal with and fortunately it's all fully detailed in your specific test), I'll start with the swimming pool.
The mode of operation is very simple. The internal accelerometer of the watch (the same one used to count steps on the activity monitor or the cadence while running) is capable of counting the number of strokes. And not only that, it can also identify when you have reached the end of the street and make the turn to face another length.
It is therefore capable of accumulating distance with quite high precision. It can always miss some lengths, but usually it is more our fault when making strange movements with the arm than a problem with the watch. But it also allows us to count the number of strokes needed for each length (the fewer strokes, the better you slide) and therefore the value of the SWOLF.
The first time you access the swimming profile you will be asked for the size of the pool. You can choose from the different standard pool sizes (25 meters, 50 meters, etc.) or enter a custom size, starting at 17 meters. If at any time you change pools and are going to swim in a different one of greater or lesser size, you must enter the activity profile configuration and make the appropriate modification.
In the swimming profile the data screens we can configure are very different from the running or cycling ones. Obviously the sport has nothing to do with it, so there will be a lot of variation. Strokes, SWOLF, average interval or 100m rhythm... all that is what we will be looking at now. We have the same number of editable screens (four), as well as the possibility of configuring alerts for distance, calories, etc. Everything is the same as in the previous profiles.
But there are different options. For example, you can turn the stroke type detection on or off.
That way, when you synchronise your activity and check it out in Garmin Connect, you'll know what you were doing in each exercise, since we usually work on multiple styles in the pool. If you only swim crawl, you can totally forget about it; but if you do multiple styles, it's always helpful to be able to check out all the details in Connect.
There is also a screen that you can activate to do the exercise log. For example when you have to do crawl feet holding a board. In that case there is no arm movement, so the watch cannot register distances. You can activate the technique exercise log mode and when you finish, it will ask you the distance you have swum. That way those meters will also be added to the total of the session (it is important to synchronize with Strava all the meters you have done, so that nobody sees that you are skipping).
Along with the introduction of the Forerunner 735XT, Garmin introduced another important new feature for the swimming profile (which also reached Phoenix 3 and Forerunner 920XT) The advanced training has also reached the pool, which is perhaps where we missed it most. No more arriving at the pool loaded with pull buoy, fins, shovels... and a piece of paper in a plastic cover with all the exercises we have to do.
Now you can prepare your training session and synchronize it with the clock. The screen will show you the different exercises you need to do and you will go through all the steps in the same way as when you have prepared a cycling or running training.
In addition, after the latest firmware version 3.30, icons are also added to reflect the material to be used in each part of the training.
Another novelty that has arrived at the 735XT exclusively is in the records. Although I have not specified it in the previous sections, the 735XT keeps track of the records you are making for different distances or other parameters. For example, for running it will record the fastest kilometer, the best time in half marathon, the longest run, etc. Similarly, in cycling you will be able to see the best average power for 20 minutes or longer.
In the 735XT these records also come to swimming, being recorded the times for the fastest 100m, 400m or longest distance. These records are only for swimming in the pool (it does not compute in open water, so if you do 2,500m in the sea but your pool sessions are usually 1,800m, the record that will appear on the watch will be the 1,800m). All these records will be synchronized with Garmin Connect and podrans to see them in the "Personal Records" tab, although as of today it does not yet show the swimming ones.
And as usual, after finishing the training and synchronizing it, you will be able to access all the details
But if you want to know all the details, I recommend that you take a look at the corresponding article in Garmin Connect data analysis.
Open water swimming
Swimming in open water means any swimming exercise outside a pool of a certain size. Here the distance and the rhythms are not determined by the internal accelerometer of the watch, but by the GPS (although the accelerometer will still provide information on strokes per minute and SWOLF).
Without a doubt, the most difficult task that a GPS watch can face is swimming in open water. The reason is simple, every time the watch enters the water (with each stroke) the GPS signal is lost, and it recovers it (or has to try) in the short time that the arm is out of the water.
From this data, the watch has to join a series of location points and try to interpret the route you have followed. From this route it can give you information about the distance covered and obviously about your swimming pace.
The result obtained with the 735XT has been really good in all the tests that I have done, both for the route followed and for the calculation of distances, for example this training, following the line of buoys parallel to the coast, coinciding both to the go and to the return.
To test him, he wore a total of four watches to measure the route. On both arms, watches capable of swimming in open water: Garmin Fenix 3, Suunto Ambit3 Sport and the Garmin Forerunner 735XT itself. And as a judge of all of them, a Garmin Forerunner 230 underneath the swim cap that, in that position, is always kept out of the water and will therefore correctly mark the route followed.
These are the distances recorded by each of them for this training:
- Garmin Forerunner 230 (which is the one that marks the "real" distance): 1,560 meters
- Garmin Forerunner 735XT: 1,660 meters
- Garmin Fenix 3: 1,602 meters
- Suunto Ambit3 Sport: 1,817 meters
The following is a comparison of the four recorded tracks, the most lost being Ambit3, which is a little more dizzy, while the other three are quite well covered.
As far as heart rate is concerned, you should remember that the Garmin 735XT does not allow you to use its optical pulse sensor when performing water activity. The reason is that to date no optical sensor is capable of accurately recording the pulse under water. I have tried several sensors (both clock integrated and external) and sometimes I got good results, but at other times it was a complete disaster.
On the 735XT we can use the HRM-Swim or HRM-Tri sensors to obtain the heart rate data for further analysis after synchronizing the training.
You can find all the details of these sensors in the specific test they have dedicated.
Triathlon and multisport
Without a doubt, what makes the 735XT a special watch is the possibility of linking several sports in a consecutive way, mainly the three I have detailed so far.
That is, to be able to record each segment of a triathlon independently, each in its application profile, and present a complete activity in which we can even include the transition times.
Because there are many watches capable of recording swimming, cycling and running activities (even within the brand itself, such as the Vivoactive). But they lack the possibility of concatenating these activities. And not only for triathlon, but for any competition in which more than two disciplines are involved: aquathlon, duathlon, etc. And of course, also block training that you want to record in a combined way.
Once you have all the individual sports set up (i.e. if you are setting up a triathlon activity: swimming in open water, cycling and running), you can create a new multi-sport application by simply going to Settings and Activity Profiles.
And you add a new activity, in which you select the Multisport option
You can enter the name of the ones you suggest (triathlon, duathlon or block), or you can customize it with the name you want. And it is already a matter of choosing the sports that will make up the multi-sport activity. These activity profiles you are selecting are the ones you have already created and configured previously, so if you want to have a specific race profile with different data screens than the ones you use when training, you must have created that profile previously.
You can also choose to include transitions or not. The transitions will be an intermediate activity that is separated from the rest and recorded independently. To go from one activity to another you will do it by pressing the turn button, so when you get out of the water, you will simply press the button to start T1.
After taking off your neoprene, putting on your helmet and so on, you can press the lap button again before getting on the bike and then go on to the next activity you have programmed (in the case of a triathlon, cycling). The watch will finish counting the time of T1 and start counting the time of the cycling segment, and so on until the end of the race, when after the last press of the lap button the activity will be finished.
Within the data screens you can have the time of the current activity (e.g. running) or the total time of the test, depending on what you prefer in each moment.
When synchronizing the activity, in Garmin Connect you can access the complete activity, and at the top you have several tabs to switch between different sports, for example this block training.
The first screen includes both activities with the basic details of them, but you can go from one to the other in the upper tab and consult each of the sports individually.
And the same thing if what you do is a triathlon.
If you have set up automatic synchronization of activities with other platforms (Strava, Training Peaks, etc.), Connect will send each part of the training independently, including the transitions. So if you have a triathlon in Connect in a single activity, five activities (the three segments plus the two transitions) arrive in Strava. Only Garmin Connect performs this grouping.
The only thing you need to keep in mind when doing this kind of training is that, since the lap button is the one used to switch between activities, you cannot use it to separate laps or parts of the training.
But there is another option when it comes to consecutive workouts. If you press and hold the scroll down button during an activity, you will access the activity menu. You can switch to any other activity and continue recording the same initial activity (i.e. all in the same file). This way you can use the lap button anywhere in the workout, but you will not save the transition time.
The Garmin 735XT is not intended to be a navigation aid. Many of the features that can be found on the Fenix 3 are not present on the 735XT. We cannot scroll the map left or right to see other areas of the route.
But there is one aspect of navigation that improves the Fenix 3, and that is that if a route is created from Garmin Connect and sent to the clock, it will include landmarks in the route. This allows you to have turn-by-turn navigation A warning appears on the screen not only indicating the distance to the next turn, but also emitting a warning tone (and vibration) when we are about to reach that point.
These directions are primarily intended for use when using your cycling watch, as it will give you advance notice of a detour. It is not point-to-point navigation like the one offered by an Edge 1000 computer (which includes maps), where you mark that you want to go to the nearest McDonald's to continue your diet and automatically plot the route; but it does go beyond the typical point-to-point route.
You can zoom in and out on the map.
To access the menu, simply press and hold the top scroll key while on the map screen.
In addition to the directions themselves, other information screens will be added regarding the route, such as a virtual partner (you have to indicate the estimated pace or speed when creating the route) or the remaining distance and time.
The navigation menu includes a couple of other possibilities. First, you have an option to provide positioning data for a certain point. You can save that place to come back to later (for example, where you parked your car).
However, the route will be simple with an arrow that will indicate the direction you should take, there will be no indications of turn because logically it is not a saved route.
Secondly, you have the option of returning to the start. You can activate the map view on the clock with no route and you will see that it saves where you are moving. If you activate the option of returning to the start, the clock will show the direction indication with the arrow, as well as the map to retrace the route (if you activate the map screen). You will return by the same route, not by the possible shorter route (because I repeat, the clock does not have any cartography).
This option can be found both in the main menu and in the activity menu (which is where you will need it most). To activate it, you simply have to hold down the scroll up button to access the menu where you will find the different options.
Optical heart rate sensor
Even though the Garmin Elevate sensor of the 735XT is already an old acquaintance, in each new clock that includes it I like to repeat the pulse graph comparisons. The physical hardware is the same and there are no variations in that aspect, but the algorithm does get polished with each version, both in the new clocks and in the previous ones, through firmware updates.
I remember that the main problem with the sensor was with the interval activities and the delay in recovering the pulse, which always took a little longer compared to other sensors (both optical and chest). I have seen quite a few improvements in that area.
The second point where it is difficult is when riding the bike, since the algorithm must work differently because the same movements are not made, as well as the forced position of the wrist, which can facilitate the entry of light into the sensor area. And here ... because everything remains virtually the same.
In short, in the race he has improved his behavior significantly, which does not mean he is perfect. He still has his problems here and there.
Here are some comparative tests in which I compare the Garmin Elevate sensor of the 735XT with other sensors, both optical (Scosche RHYTHM+) such as the Suunto Smart Sensor or the Garmin HRM-Tri. Obviously, I perform these tests based on my skin and hair characteristics, etc.
Note that there can be differences from one wearer to another, but the most important thing is how it is worn on the wrist. Firm (not strangled) and leaving a space of approximately one finger between the wrist bone and where the watch is placed.
I specify this because later in the comments I am accused of lying or of putting perfect graphics, and when someone buys it and tries it they have other results (because of their skin or because they don't put it on properly). I repeat, it is my experience in my body and knowing how to put the watch on my wrist.
As I said, I've seen improvements in the sensor, but that doesn't mean that the sensor doesn't have its problems, as in this workout that should be fairly simple (constant pace) and yet the Forerunner 735XT was totally lost just over 10 minutes, despite starting perfectly and not being a particularly complicated workout.
If I have to bet on something, I'd say it's a problem with strap adjustment and sweat accumulation. Maybe I should have taken an extra tightening point, to prevent sweat accumulation under the sensor.
In the next workout something similar happens again. The start is good, even at the first peak of effort. It was time to run with 5 30-second intervals at a sub 3:30 pace. In the first one everything appears quite well, even without the usual delay in the pulse recovery of the Garmin Elevate sensor.
The second peak has a slight delay, but in the stretch from the third to the fourth interval we can appreciate another common problem of the optical pulse sensors (not only Garmin's, but all sensors of this type).
This problem, called "cadence lock", occurs when the sensor confuses the movements of running (i.e. our cadence) with the beats per minute. What the algorithm does is to eliminate the signal noise produced by the cadence to determine the beats per minute; if there is a problem when recording is when problems arise. In this picture you can clearly see how the sensor has been thrown off by the cadence instead of continuing to read the heart rate. This is something that neither of the other two sensors (nor the other optical sensor, the Scosche) had this time, but it could have happened to the other optical sensor as well.
This other test is much more complicated. 20 second sprints with recovery walking to the starting point. We have two different parts, first the continuous race with quite stable pulse at the beginning and at the end of the training. Here both the sensor of the 735XT and the Suunto Smart Sensor match quite satisfactorily.
But on the 10-sprint leg, Garmin struggles, but fails to get a correct reading. It starts well, albeit slightly late in the first moments of each interval, but recovery is always immediate, something that Garmin Elevate had a hard time with.
But as I'm melting down in training, the 735XT's sensor is getting harder and harder and is not even able to reach the pulse peaks that the Ambit3 does.
As far as cycling is concerned, it is still a rather difficult activity, so why deny it. There are times when the recording is correct, and others when it doesn't. For example, in this training, and except for the start (which is always more complicated for any device), the recording is quite satisfactory. Even so, for cycling I would prefer to always have the pulse sensor on my chest.
These errors are caused by light entering the sensor's reading zone, as well as by potholes in the road and other typical movements in the bike.
By training indoors with a roller, where you won't find many bumps (or so I hope...) and with less light, the sensor is able to perfectly register the pulses, regardless of the intensity of the exercise.
You can see how, except for a sprint at the end where it is not mentioned (marked with a circle), in the rest of the activity it registers perfectly together with the other sensors.
The sensor doesn't look as bad as it seems because of the tests I've done before. I just wanted to point out the most complicated moments where I've been able to appreciate mistakes. Because putting any other graphic I have that matches almost perfectly would be very boring, it's always better to put some pepper on it.
That there are also, for example, a training in which in addition to running, it includes 10 stops to make twelve side jumps to each side. The result? Three perfectly aligned graphs from beginning to end, including the stops to make the corresponding jumps.
It may seem that I'm simply taking data from an external sensor, right? Not at all, here you can see a magnified area and you'll see that there are slight differences between the three sensors.
You simply have to assume that, for the time being, performance is adequate for what kind of activities. Continuous running or constant pace competition? No problem, it could perfectly go with just the optical sensor. Cycling or interval training? If you want to have accurate heart rate data, you should think about using a chest pulse sensor.
I'll try not to extend too much in this section because you'll find in this option basically the same as in the Forerunner 235.
You can find the activity monitor in one of the available widgets. Simply by pressing the scroll button you can reach its screen. Here you can see the number of steps you have accumulated during the day along with a bar that will be completed as you reach your goal.
This target can be set manually (for example, 10,000 steps), although I find it more interesting to leave it as it is by default, allowing the clock to automatically adjust the target according to your trend.
By pressing the main button on that screen you can see the record of the previous seven days, and you can check if you have reached the goal in each of them and what is the trend you are taking.
The clock shows, next to a red bar, warnings of inactivity. If you spend too much time without walking the clock will warn you to stand up and walk a little, with the intention of staying active. To remove this bar you must walk for about 200 meters.
However, if you don't want these warnings, you can turn the function off and lie on the couch without any conscience.
As with Forerunner 235, the Garmin Elevate pulse sensor records heartbeats throughout the day. The recording rate is variable, with no movement taking place every few minutes and more movement taking place over shorter periods. The watch has a graph of your heart rate for the last 4 hours, along with the minimum and maximum heart rate for that period. At the top of the screen you can also see your resting heart rate for that day.
One problem that Garmin has not yet been able to solve is the lack of correlation between different values. It is common for the resting heart rate to be higher than the minimum shown on the graph. According to Garmin, the resting heart rate will correspond to the minimum average over a longer period of time, not the absolute minimum for the whole day. But since the recording time is quite long when no movement is detected, the calculation is not as accurate as it should be.
For example, right now, as I write this, my resting heart rate is 53 beats, while the minimum for the last 4 hours is 46. This only creates confusion, because if you don't explain what RCF is and how it is calculated, then the confusion comes.
And just like the step widget, pressing the main button will access the graph with the resting heart rate for the last 7 days, allowing you to see if there are any strange spikes or trends that may indicate you are over-training or fatigued.
Finally, if you sleep with the watch you will also have information about how your sleep period has been. In this case the information is much simpler, indicating only when you have had periods of deep or light sleep, along with the total number of hours of rest. This does not appear on the watch, but you can consult the details in the mobile application.
All of this data is also part of Garmin Connect, and you can view it in the web application as well (both the sleep data and the rest of the activity).
Like in the mobile application.
One of the most criticized aspects of the Forerunner 735XT is the autonomyFor this model, Garmin announces up to 14 hours in GPS mode (GLONASS off) and optical heart rate. This is more than enough time for almost everything except long distance. Depending on your level, those 14 hours can be a lot or a few.
The 920XT would be able to handle an Ironman without any problems, but some users might need to do some tricks to make the new 735XT last the whole race.
With the 735XT's range test I have another problem. Unlike other Garmin models that use this same optical pulse sensor, after a few minutes without movement the watch deactivates the sensor. Therefore I cannot repeat my usual procedure of leaving the watch on the roof recording an activity and waiting for the battery to run out.
Yes, when I left it and started the activity the sensor was on, but every time I went to check how the duration was going I found the sensor lights off. As soon as I picked it up and there was movement, they came on again.
However and for comparison, here is the result of the complete test. The conditions were only GPS activated (without GLONASS), without connecting external sensors and although the optical pulse sensor was activated, it did not work for the reasons previously explained.
Is the data provided by Garmin reliable? I recall that the manufacturer specifies the following:
- Up to 14 hours in GPS mode with optical sensor activated
- Up to 24 hours in UltraTrac mode, without activating the optical sensor
- Up to 11 days in clock mode, with activity monitor, heart rate tracking and smart notifications
But I am not in a position to confirm or deny this. As appealing as it may seem, doing an activity of more than 14 hours with the watch is not something that particularly appeals to me. The experience with other watches (both from Garmin and other manufacturers), together with the results of the test in their specific conditions do make me think that the data provided on autonomy are accurate, both in activity and in daily use, in which I have needed to charge the watch every 6 or 7 days (those 11 days would be without recording a single activity).
In short, unless you are planning to participate in long-distance trials and estimate that you will need more than 13 hours, the range offered by the 735XT will be sufficient.
One of the main advantages of inheriting hardware that is already present in other ranges is that there is not much work to be done in adjusting the behavior of the chipset and antenna. 230 and 235 did not have any problems in their GPS and, evidently, the 735XT (with which it shares most of its hardware) did not either.
It is common to see certain problems in new models, which are usually polished in successive firmware versions. And Garmin knows a lot about this, since with some of its models they have gone through a lot of problems (the beginnings of the Fenix 3 were complicated in areas of difficult coverage). But the 735XT is totally reliable from the beginning, even in open water swimming.
In the many trainings I've done together with other devices I haven't seen any kind of problem in terms of GPS reception. Of course there will always be some clipped corner here or there, although this will always happen with any device. But there hasn't been a single moment when I've seen strange tracks or unbalanced rhythms on the clock screen.
For example, here is a comparison of the Edge 520 mounted on the handlebars, both when drawing the route on the road and when turning the roundabout, which is perfect in both cases.
The same applies to recovering signal after a momentary loss, such as when passing under a bridge. A small deviation of the two units can be seen (less than one meter) to recover the same line shortly afterwards.
As I say, there is no perfect device, and in difficult areas there will obviously be cuts in the turns. Still, in narrow streets with buildings, it doesn't do strange tracks either.
The tone is the same in training, but with perfect visibility of the sky, there are no details to highlight.
In difficult areas with many trees all devices suffer, but still the result is good, improving the Forerunner 230 and also the Ambit3 Vertical, for example in this curve where on the way up and on the way back I pass through the same corner stuck to the kerb.
In that corner the Ambit3 Vertical goes 2-3 meters to one side while the 230 cuts the corner a little bit (although because of its placement in the arm, this last one has it much more complicated). On the other hand, you can appreciate how the 735XT records the two different lines to reach that point, and how both to go and to come back the turn in that curve is made in the same place, as it actually happened.
Even in recurring workouts in the same area (as in this series of short, high-intensity intervals) where, time and again, it comes back to the same pivot point. Instead, the Ambit3 Vertical steps on the grass from time to time and shows a slightly more erratic line.
It doesn't mean that it doesn't do strange things. For example, a little later in this training it performs a strange cut and turn, which the Vertical Ambit3 has no problem tracing correctly.
I could keep adding captures from different points, compared to any other device, but it's really not worth it. In each and every activity I've done, I haven't been able to appreciate any kind of problem, because for that, as you'll see below, there's already the issue of the barometric altimeter.
Altimeter (or lack thereof)
One of the most noticeable absences on the Forerunner 735XT is the barometric altimeter - not because it's necessary or not (that already depends on your personal needs and the type of training you do), but because it's something that was present on the 920XT and that to do without it on the 735XT seems a clear step backwards.
Some will say that after synchronizing the activity the altitude data is perfectly in the analysis of the activity, and they are absolutely right. For example this activity in which I have been glued to the sea, making a route as flat as a plate. Yes, the route recorded with the 735XT appears perfectly flat. But it has a trick.
After synchronizing the activity, online applications usually delete the altitude data recorded by the GPS and correct all the elevation data, replacing it with mapping data. You can see this in any Garmin Connect activity, below the clock image you will see that the altitude correction is always on for clocks without a barometric altimeter.
In the case of watches that do have a barometric altimeter, it will take the data recorded by the watch.
But that's not the actual data you'll see during the activity. You can activate an altitude field, but it will take the data via GPS. And that record can be anything but reliable (GPS is designed to be accurate in 2D, but not in 3D).
It may be that in your training sessions you usually run on mainly flat routes and don't pay attention to the meters you climb, in which case the altitude is something you can totally rule out.
But in cycling, if you like to see the positive meters that you have accumulated after passing through several ports, you will not be able to do it in the middle of your activity, you will have to wait to synchronize because the data you count on in the middle of your training is totally useless.
As you can see, I'm right next to the sea, so there's hardly any altitude to gain. I wear a watch with a barometric altimeter (Suunto Ambit3 Vertical), while Forerunner 230 and Forerunner 735XT only record altitude via GPS data.
Beyond the scale in which they are (I do not usually do altitude calibration unless I have very clear that I will do a "high altitude" training), you can see that the barometric altimeter of the Ambit3 is slightly high that day (because of the atmospheric pressure), you can see how once you reach almost sea level, the record of the Suunto is practically a straight line, with the slight variations of going up or down a meter.
The two Garmin models, on the other hand, trace the unrealistic record of altitude, making constant ascents and descents. Yes, the trend is similar, but the accumulated meters of ascent and descent will be much greater in the case of the two models without the barometric altimeter.
And this is in a totally flat racing training. Imagine that you climb a pass with 700 real meters. The 735XT will be able to mark you perfectly 1100 vertical meters (or even more).
If your cycling or running training is mainly on a flat track, it won't affect you. Or if you use a cycling computer with its own altimeter for your cycling. But it's something to keep in mind.
The absence of the barometric altimeter also has a minor impact on the activity monitor, as you will see below, because unlike other models (even lower range), it will not be able to count the number of floors climbed or lowered.
In addition to all of the above, don't forget that Forerunner 735XT also has a smart watch function. Thanks to Bluetooth connectivity (for data only, not sensors) the watch interacts with your mobile phone, just like any other Garmin watch in recent years and almost all of today's sports watches.
So you'll have on-screen notifications (which you can only view, but not interact with as you can with Apple Watch or Android Wear watches) or synchronize activity and activity monitor data automatically and wirelessly.
The notification platform continues to be improved, because until now emoticons were not displayed on screen, but the latest version 3.30 includes support for displaying them, improving notifications a bit more. However, there are still some problems when displaying notifications, especially if they are multiple notifications from the same application (for example, messages from various WhatsApp contacts).
While you're running or practicing any other activity, there are other features you can enjoy as well, as long as you have your phone with you.
For example, the phone provides spoken messages with distance and speed alerts, if you have set this up in the application.
You will also be able to do LiveTrack, being able to send a link to family or friends who will be able to follow your training live. Not only the location, but also metrics like speed, heart rate, etc.
Both the mobile notifications and the other options depend directly on the mobile application, which is available for Android, iOS and also Windows Phone. Remember an important detail, you must pair the watch through the application, and not from the phone's Bluetooth settings.
Finally, like all Garmin models in recent years, the 735XT is compatible with the Connect IQBut with an important new feature, it has more memory capacity and is directly compatible with the latest version of Connect IQ (Biker MonkeyAlthough there are currently no differences between the first and second versions of Connect IQ, it is foreseeable that later on we will start to see some fragmentation in the type of applications that can be installed in the first models or in the latest ones adapted to this new version.
Errors and bugs
Despite being a clock that comes in a well tested package (because it shares most of its hardware with the rest of the Forerunner range), in these first versions it's not exempt of some minor problems. They are easy to fix and will surely be solved in the next update that the clock receives, however I always like to highlight them separately. But today in its 3.30 version these are the problems I've found:
- Sometimes it doesn't connect to external cycling sensors automatically, for example with power meters or cadence and speed sensors. In some training sessions I have collected power data from the Edge 520, but inexplicably the 735XT didn't connect. It has also happened to me with the Garmin Varia radarIf I made the connection manually then there was no problem, but if there were problems with disconnections, sometimes I would reconnect and sometimes I would have to turn the radar off and on so that both devices would be connected again.
- Along with the above problem, there is another one, and that is that it is not possible to access the menu from within the activity. Not at all. Just change data fields of the selected screen. Neither calibrate the power meter, nor connect to another sensor (for when it has not been connected correctly), nothing. And this, without a doubt, is the most important problem since it limits its use if you do not want to leave the current activity.
- After running the battery test and letting the watch run out of battery power, you lost the language file. When you turned it back on, it had lost the time, but the language had also been set to English. Within the setup menu, the Spanish language was not present. If this happens to you, you will need to connect the watch to your computer and install the language through Garmin Express.
Despite this, the software is quite stable today, but everything can be improved, and Garmin needs to solve the small problems detailed above.
Buy Garmin Forerunner 735XT
If you want to collaborate with the site and help it to continue to carry out tests as extensive as this one (which requires many hours of work), buy your watch through the links I provide. That way I will receive a small commission at no cost to you. And don't forget to share the test with your friends, besides helping me your friends will be tremendously grateful to discover this site.
There are several packs that you can buy, depending on the content of the pack. And in each pack you can choose the color of the watch (between black or blue, both of which you can see in the photos of the test). To summarize, you can buy the Garmin 735XT in any of these ways:
- Garmin Forerunner 735XT watch onlyYou'll have an optical pulse sensor, but no advanced running metrics, lactate test or heart rate in swimming, for example.
- Garmin Forerunner 735XT pack runIt includes the HRM-Run v2 sensor (the red one), which you can use to have all the advanced running data as well as to have more precision on the days of the series or cycling.
- Garmin Forerunner 735XT Tri packIt includes the HRM-Tri and HRM-Swim sensorsso you'll have it all.
This is the Run pack
And finally, the Tri pack
Review Garmin Forerunner 735XT
The Forerunner 735XT is a VERY complete watch, I have no doubt. It will satisfy the vast majority of users. In fact, it includes some features not yet seen in other models (swimming records, advanced swimming training that was released with this model, navigation with directions, compatibility with Varia Radar and Varia Vision, etc.). Unfortunately, there are some shortcomings that cast a shadow over the whole.
As a race clock, it behaves perfectly, with the same options you'd find in the Forerunner 630. In fact, it's what many users have been asking for - a Garmin Forerunner 635 with an optical pulse sensor, because there's very little difference between the two models. Besides the sensor, only the touch screen and WiFi connectivity - that's what anyone is willing to do without.
But it is strange in a watch with so many roots in cycling the absence of a barometric altimeter. To face training where you have to cross mountain passes and look for a certain accumulated unevenness (we all have trainings of this kind from time to time, our trainers like to see us suffer) is much more complicated with the 735XT, and that is because the altitude based on GPS is basically useless. Yes, after the synchronization of the activity the altitude data will be corrected, but while training you will be practically blind.
Another aspect to consider is the autonomy, at least if you plan to compete in long distance. Depending on your racing expectations, the 14 hours with the use of optical pulse sensor can be short for some, although I don't think that's the factor that more people will turn back.
Far from Forerunner 735XT's impressive list of specs, what I miss most about it is personality. Until now, Garmin's multisport range has always been special in design. Everyone that ends up in XT has always been aesthetically different watches. When you saw someone with a 310XT, 910XT or 920XT you knew their wearer was just as crazy as you are. It's not enough to swim, run or ride a bike; you have to do it all. It's seeing the watch and crossing a complicit gaze.
The 735XT has undoubtedly improved in aesthetics (not in materials), with a smaller size and a much more standardized shape. I think you'll agree that the 735XT is much nicer than the previous saga. But it has lost its soul to become another model in the Forerunner range. It's a very capable watch, but it lacks charisma. And beyond the absence of a barometric altimeter, it's the only thing I miss, being different
Thank you for reading and supporting the page!
Garmin Forerunner 735xt vs Garmin Fenix 3 HR... if you were given one as a gift you would choose... 3 quick motives... thank you very much for your analysis!
Aesthetically I like the Phoenix 3 better and it has a barometric altimeter.
But the 735XT being newer has some more features, especially in cycling.
Difficult decision, values the issue of size and weight on the wrist, is the most important difference.
I join the indecision 🙂
I am considering the 735xt option as well, in my case for the following reasons:
- lightness of purpose
- I have an ambit2 that I would reserve for when I need the barometer or navigation (kicking routes in the mountains, following wikiloc routes, ...). I would reserve that role for you and the other for training and competition.
- and above all I'm motivated by the option of the various radar warnings on my wrist...at the bike's exits.
How do you see it?
Greetings and thank you, crack!
Well, no objection, especially since Varia Radar doesn't look like it's going to make it to the Fenix 3 (they're saving it for 4).
And with an Ambit2 reserved, you'll have mountain activities more than covered.
For most users it is more versatile and comfortable, size, discretion, weight ...
If you're going to IM and you're not very fast, maybe the battery will run out and you'll have to go to 920. The Fenix is very stubby, nice... but maybe for mountain alone.
Sprint triathletes, olympians, media...Multisportsmen is the ideal audience for this sportmartwatch
Fantastic test. Congratulations.
Which speed/cadence sensor pack do you recommend for the 735xt?
I was thinking about the wahoo fitness RPM, because of the duality ANT+ and BT. Do you see it well for the garmin, or maybe the brand itself?
Indeed, the one I recommend is Wahoo's: https://www.correrunamaraton.com/mejor-reloj-gps-2016-2017/#SensoresI wouldn't choose any other option but ANT+.
Hi, I just got my garmin fènix 3, do you think the next software updates will include the lactate threshold, navigation with directions and turns? Thank you very much
The Fenix 3 already has the lactate threshold calculation. As for the turn signal navigation, I doubt it will get it.
I have a Suunto Ambit 2 and now that I can make a change I'd like something lighter and less touchy, so I can wear it every day.
I've been reading your reviews on the Garmin 735 XT, the 920 XT and the Polar V800 and the truth is that I'm a mess... I'm looking for something to go out and run on the asphalt and dirt, some trekking and some time swimming in an outdoor pool.
Thank you very much.
If you take into account the absence of a barometric altimeter and don't worry too much, the 735XT is the best choice. And more now with the price you have on Retto.
Thank you very much for everything.
At the moment the absence of a barometric altimeter doesn't worry me, but I do look at how this unit is coming out and that being plastic it doesn't look a bit flimsy.
I barely knew your site and I'm loving it.
One thing that is not clear to me; you have vibration alerts in the different sports... (if I go past 4.30 running or 1.30 swimming for example, or every so often I vibrate...)
Yes, for each sport you can set up specific alerts
Sorry about the message before, but this is the first time I've done any of this.
In the open water comparison you also compare the results with the forerunner 230.
The 230 can also be used for swimming in open water?
Measures the distance swam?
It's just that I read your analysis of him and I didn't find anything that refers to swimming.
Thank you very much in advance and congratulations for the great work done.
The Forerunner230 has no swimming metrics.
But of course, if you wear it under your swimming cap, as tightly as possible, you can end up getting the "approximate" swimming course. As for example many of us have done with the garmin305 😛 on the head!!! what a time!!!! hehehehe
Exactly, as Xavi says the 230 has no metrics, I simply wear it under my swim cap to get more accurate distance data by always wearing it above water.
If it goes on the wrist, kittens die...
Thank you both very much.
I'm new at this and I really have a lot to learn.
See if you can help me.
I'm looking for a gps heart rate monitor that I can use for running, cycling and swimming in open water (without having to put it in my swim cap ;-)), although it doesn't need to be used for triathlon.
I'm also looking for a tracker.
I like this 735xt a lot but it's a bit pricey.
Thank you very much for everything and congratulations on the great work.
You can use the Ambit3 Sport, which right now has an authentic price offer on Amazon: https://www.amazon.es/gp/offer-listing/B00MN96TXS/ref=as_li_ss_tl?ie=UTF8&condition=new&linkCode=sl2&tag=c1mes-21&linkId=e69545f020102679dea3e2cc9ff674c9
Thank you very much for your quick response.
I'll take a look at it.
Hi, I've been reading the description and I'm left with one question... Do you have a stopwatch?
Not a separate stopwatch. You have the activity time.
Thank you very much for this piece of analysis and congratulations on this great blog! It's a real detailed guide and instruction manual! I'm looking for a watch that will improve my cardio tomtom runner. My activities are running, outdoor and indoor cycling and swimming, for now only in the pool, but I aspire to do triathlon, so I'm aiming for this kind of watch. I have several questions.
The first one is: Can you download routes like, for example, from wikiloc? I don't think so, because I haven't read it anywhere, but it's better to ask.
Another: To increase battery life and if you don't want it to be "spying" on you all day long, is it possible to disable the functions of a smartband: continuous heart rate monitoring, sleep analysis, alerts to move, etc.?
The third is: I have read that, at present, there is no optical sensor that works properly underwater, so to have heart rate readings in water, the band is necessary, as well as for other complex metrics, both cycling and running. How close do you think the optical sensor is to "retiring" the chest bands? As far as you can tell is this very close and worth waiting for or is it still a long way off?
The last one is: I have been evaluating other cheaper devices, like the Tomtom Adventurer, more than anything else, instead of the Tomtom Runner 3 because the Adventurer has the altimeter and, although it is more designed for mountain sports, it also includes modes of the sports I practice. I know that neither the Adventurer nor the Runner 3 are triathlon watches, they don't measure intervals, etc. I have discarded Fenix 3 HR type options because the top of my budget is the 735XT (the wrist pulse sensor option is vital for me). The question is: Knowing what I have told you, would you take the Adventurer or the 735xt? Or maybe you would recommend another one that escapes me?
Thank you very much for everything and regards
Right now you have the 735XT on sale at Retto, take a look: http://www.retto.com/ciclismo/fasts/735xt.aspx?belboon=037c4b091af20400d8004e80,4275199,&utm_source=belb_es&utm_medium=cpa&utm_campaign=262360
In Wikiloc, in fact, you can install directly on Garmin (from a browser like Chrome), but you can put any path in memory in TCX format and it will accept it (via cable).
You can turn off the optical sensor, not the activity monitor, but the monitor does not consume battery power.
At the moment the optical sensors are not able to read pulse variability or work properly under water, the former is being worked on, for the latter I don't think there will be solutions soon.
If you're planning on doing a triathlon, don't hesitate, the 735XT.
Thank you so much for clearing up my doubts! I think I'll go with this watch.
You're welcome. By the way, I just updated the Black Friday ticket with some more 735XT offers: https://www.correrunamaraton.com/black-friday-2016/
Hi, Eduardo, great analysis. Could you quickly compare it to the V800? I'm hesitating between the two... Thank you!
Unless the price is the most important factor in the choice (especially if you want to have pulse data in swimming), the Garmin is far superior to the Polar. And the almost two years difference between them is quite noticeable...
Don't you get pulse data in swimming pool and open water swimming with the V800? I thought the H7 band was compatible underwater with the V800 and that it got HR variation data...
I mean, on the V800 you have the FC data with the sensor included, while on the Garmin you have to buy the pack with the HRM-Tri or HRM-Swim sensor
Very good Eduardo. I am quite convinced with this watch. I have been told very well about Garmin and I like both the design and the features. My only problem is that every time I run (and it is what I do most), I like to go with music and it is annoying to have to carry the mobile as well. You think that if I wait, new Garmins with that feature could arrive. I tried the tom tom and I didn't like it at all. Polar m600 gives me the feeling of being a lower range than this Garmin. I don't know, I would like to know your opinion. Thank you!
At the moment, it doesn't look like Garmin is going to bet on having a watch with music support. The main drawback they don't want to have is the decrease in battery life.
Hi Eduardo! First of all congratulations and thanks for the blog, it's amazing how easy you make life for us amateur athletes.
I'll tell you my situation: I want to renew my old forerunner 210 and since I've been cycling lately and I'm starting to run quite a few trails I'm quite disappointed that the 735XT doesn't have a barometric altimeter because it was my main option and it seems too expensive for me to run at half gas on a trail.
I would like to buy a multipurpose watch that would allow me to keep track of my recovery, get enough information from the sensors and perform well on the trail. In the long term I aspire to do a triathlon although at the moment my basic disciplines are running, cycling and trail. My wrist is not very big so I am a bit lazy with the fenix so I don't know if I only have the option of the v800 or if there is something else that can be adapted to my situation.
Thank you very much in advance.
Of all those, the most contained size is the V800. You also have the Suunto Ambit3 Vertical or Ambit3 Peak, but they are similar in size to the Fenix 3.
Thank you very much for your blog. I am writing to you from Colombia.
Before reading your review I had already bought this 735XT. Like Javi, what I practice most is running and cycling and I have the desire to jump into triathlon, so that's why I have dedicated myself to this watch, taking into account the cost-benefit ratio.
Of all that you tell us, what I really regret the most is that it does not have a barometric altimeter, you know that here in Colombia what is most important are the mountains of the Andes.
I really liked your analysis and you give very clear hints to use it.
Thank you, David.
The difference will be if you want to know altitude data during training. If you are not concerned at that time, after synchronizing the activity you will have the corrected data. Here you can find more information about the barometric altimeter..
I'm interested in garmin's 735xt, among the sports I practice are running, swimming and gymnastics, but I don't know if I can make calculations with this model of the workouts in the room, at the level of frequency, calories and upload them to the garmin's platform. I've seen that it has a function called strengh in the demonstration videos and I don't know if it serves for this or I have to look for some third party application on the platform to make this option. It could be done with the polar v800??
The truth is that after reading the last post in which you said that garmin is ahead I would be more interested in this option, you have convinced me quite a lot and I think the optical pulse is going great
For the gym, any watch will give you the same information.
Heart rate, elapsed time and calories. None have more specific parameters.
I understand then that I could use the 735 with the parameters you mentioned for the gym and put them on the garmin platform, and the rest of the activities without problems
Yes, showing time data, calories consumed, heart rate graph, etc.
Hi Eduardo! Congratulations on the blog and this article, it has been partly to blame for the purchase of my new "little toy". Yesterday I did my first pool workout with the 735. The thing is that I did a 2000, I hit the lap on the 1000 step and it stayed as in rest, even though I had disabled the option to record technique exercises and the rest screen ... I have not managed to find out how to allow me to mark the partials as I did with the 910. Thank you very much in advance, greetings!
Hi Eduardo, congratulations for the blog, your analysis and the exposition of the contents are really better than any manual. There goes my doubt: I'm looking for a watch for daily use that monitors my activity 24/7, I usually play tennis, run, bike, do some swimming and hiking, and gym. I liked the features of the vivoactive hr (although less the aesthetics), but I like the idea of more advanced training in running (and other VO2 max type metrics, recovery, etc), that's why I'm almost deciding on the 735xt (in principle the price difference I can assume). Regardless of the barometric altimeter, is there any other feature that is exclusive to the vivoactive hr or does the 735xt simply do everything of the vivoactive plus other functions?
No, everything you find in the Vivoactive HR (except the altimeter) is present in the 735XT, so if you want the extra features of this is a good choice.
Thank you for your quick response and for solving so many doubts among so many options as there are with your analysis. I will opt for this one. Thank you very much
Hi, a couple of questions,
The 920XT has the same advanced swimming training as the 735xt?
And the 3.30 firmware, with the icons to reflect the material to be used in each part of the training?
Thank you very much.
My intention was to wait for the launch of the supposed new 930xt, but the days go by and I don't know whether to wait or buy the 735xt or the 920xt...
I would basically use them for IM and Halfs.
Yes, the 920XT has advanced training and displays the equipment icons. What it doesn't have are swimming records, which the 735XT does.
Thank you very much!
Good, gengo decided to buy this watch but I have some doubts about buying the watch alone or the pack. Can you pair any band with ant+ even if it is NOT from garmin and you get the advanced running dynamics? In the pool you get the lactate threshold, with pulse or without pulse?
If I decide to take it without a tri-band, doing a triathlon when I get out of the water and start with the bike, I'll get the bike's pulsations... And roughly speaking, compensate the pack or take just the watch... Thank you very much in advance and for your fantastic website
The dynamics are exclusive to the HRM-Tri or HRM-Run sensors. Any ANT+ sensor only provides HR data. There is no lactate threshold in the pool.
As for doing the triathlon, as soon as you get out of the water the watch will connect to the sensor it is paired with.
Hi Eduardo, and first of all I appreciate your advice and the complete and detailed analysis you do in your blog.
Last month I asked you about the PolarM600 which I decided to buy to replace a Garmin FR225, the problem is that I miss options such as the possibility of configuring workouts in the watch itself, training history, and above all the battery life. At the moment I am only running and although I am a amater I am starting to be a bit of a freak about metrics (lactate, VO2 max, stride length, recovery level, etc) for all which I would need another type of sports watch with advanced racing functions. Having said that I am thinking of returning the Polar and taking a Garmin as complete as possible at an affordable price (360 ? max) and that is where the doubts between the fr630, fr735 and Fenix3 come in, in principle I find it comfortable to have an optical pulse meter, but I wouldn't mind having a chest strap if it is more comfortable than the old ones and gives me advanced functions.
- As for the advanced career features, are the 3 models mentioned equally complete? Virtual Partner, Virtual Racer, Training Effect, Virtual Pace, etc.
- Is the "back to home" function always in a straight line or can the same path be followed?
- Do all three have the stress score function and is the chest band always necessary?
- Does the Connect IQ platform v2 support all 3?
Regarding the prices, the Fenix 3 would cost me 334 Euros (272 Euros + 62 Euros for the HRM Run band), the FR735 for 360 Euros and the FR630 for 326 Euros with band included. Which option do you see as more interesting?
The new version of Connect IQ is only available for the 735XT. Both 630 and Fenix 3 lack the memory required for the new version (although there are no differences in the applications they can use today, there may be in the future).
For stress scoring, a chest sensor is necessary, since the calculation is by pulse variability (the optical sensor does not register it).
Of the three, the one with the most features (except for the altimeter) is the 735XT, at least at the software level, and it is the one that will continue to receive the most updates, since both Fenix 3 and 630 are at the end of their commercial life, which means that they will not receive any more updates.
You have the 735XT at 359 Euros through RettoRemember that by buying through the links on the website you will be helping with a small commission.
Thanks for the answer Eduardo, the truth is that I don't have it clear mainly because of the price/use ratio that I am going to give it. For current characteristics and future possibilities I would lean towards the 735, but the price of the F3 (272 euros) makes me doubt a lot, it is more than 80 euros of difference that would stay in 20 if I take the HRM band which provides more data than the optical reader but logically it is not so comfortable... If in principle it is only for running on the flat without a mountain, do you still think that the 735 is a better option? would it provide me with more important or useful functions for running?
I'll ask you two more questions and leave you alone, I'm too heavy:
- In training series, the 225, and I think also in the 235, do not show the rhythm you have taken in each interval until you finish the complete training, but I have seen that the F3 does show this data. Does the 735 show the rhythm/time after each series done?
- With regard to the return to the beginning of the route, is the same path indicated in either of the two and not in a straight line?
On any clock you can select average lap rate and know at what rate you are doing the interval. To have map back to start, it must be the Fenix 3 that is more navigation oriented.
The final decision depends more on the size desired. The Fenix 3 is considerably larger and heavier than the others.
Hi Eduardo, the average lap rate can be seen on fr225 but you don't have the possibility to see the rate of the last lap which is the one you use for the series, I understand that this data is available in all the current models. As for the function back to the start, I didn't mean a map but the arrow that indicates the way back to the start but for the same route made and not in a straight line, fr 235 I think it does like that. As for race data, is fr235 very far from fr735? I mean functions like Virtual Partner, Virtual Racer, Training Effect, Virtual Pace, etc. is that by price I am also valuing the option of fr235 that if you get it on offer (217 euros) it is more than 140 euros difference from fr735...
The back to home arrow always marks the beginning, never a path to follow. 235 does not have a Virtual Partner.
Hello, for cycling you can use the run or you have to use the tri? The tri and swim bands in cycling and swimming are used for more than just having the pulses? Thanks and a greeting
Does it have route tracking for ascents and descents like the Fenix 3? Thank you
Any ANT+ sensor will do, there is no additional information of any kind coming from the pulse sensor. Route navigation and remaining ascents are exclusive to the Fenix 3.
First of all, thanks for the great analysis. I'm about to buy the watch because of the triathlon characteristics, but I have too much HR. Do you know if garmin intends to get a 730xt like this one but without a pulse meter on the wrist? It would save something in thickness and price. And for the pulses we already have the band on the chest.
No, there won't be a 730XT. And I doubt that Garmin will ever release a watch without an optical sensor again.
Thanks for your input, it's great. I intend to give my wife a GPS heart rate monitor with meter on the wrist and I'm between the 735 xt and the phoenix 3hr, she does some training in the mountains and would need something if she ever wants to do a set route and that the heart rate monitor will indicate the route or when to turn, if it is with vibration or sound better, I do not know if the 735xt is enough or I have to go to the phoenix 3hr. The bad thing about the fénix 3hr is that I see it too big for your wrist and I do not know if the fénix 5s will be ready before February 14. What do you think? Thanks for your help
Yeah, the Phoenix 3's probably gonna be too big, too heavy.
In that sense the 735XT for her is much better resolved.
The Phoenix 5s won't arrive until the end of March or April.
Hi Eduardo, thank you very much for your analysis, very good job! it has helped me a lot to decide which "watch" to buy... I'm almost decided by the 735XT but the issue of the lack of barometric altimeter is what makes me hesitate because I run a lot on hills and cycling on mountain trails (Cross Country). Now the next question... is there an external barometric altimeter sensor that I can connect to fill this gap?
You can't add the altimeter as an external accessory. I think a watch from the Fenix range can fit you a little better.
Thank you very much!
THE WATCH IS RECOMMENDED, UNFORTUNATELY MY EXPERIENCE IS THAT IN TWO MONTHS OF USE I HAD PROBLEMS WITH THE BATTERY WHERE IT DOES NOT CHARGE THE SAME THING HAPPENED TO A FRIEND, I THINK IT IS A PROBLEM OF MANUFACTURE
I have a problem with the smart notifications. Having my phone connected to the clock, with the settings all activated, I still can't see the notifications of the e mails, incoming calls, etc. I practically threw in the towel, but I don't know if anyone can think of anything I'm not doing right with the settings or the clock.
Thank you very much!
Check the way you've paired the clock. You must do it through the application.
Greetings. I wanted to transfer a question to you. I currently have a Foreruner 620 and a Fenix 3 and the VO2max estimates give a difference of almost 5 points. Both are on the same Garmin Connect account, updated to the day and in principle with the same settings unless I missed something, which I don't think... Can this difference be normal or shouldn't it be if the settings are the same? Where could the problem be?
I don't understand anything. Thank you very much and congratulations for your information. HUGS
Sorry it's not a Fenix 3 it's a 735XT. Sorry
There shouldn't be so much variation if you use them frequently and under the same conditions, i.e. if you only make series with the 620 and quietly shoot with the 735XT there can be differences.
In my case, when I try a new Garmin with this function, after 2 or 3 weeks it always ends up indicating the same VO2max level (unit up, unit down).
I finally made up my mind and bought the 735xt, thanks in part to your comprehensive article!
I only have one question, on the main screen of the clock (when the time is displayed), a red line appears on the left side. Could you tell me what it is?
It's the inactivity bar of the activity monitor
Thank you very much!
I see that there is no option to make a track on Strava and pass it directly to 735xt.
The only way is to draw the track in garmin connect (which is cumbersome), or through the DW Map application (then you can only see the track, but you can't train and see the track).
Do you know if there's any other way we can load strava tracks into the 735?
You can follow Strava's instructions for uploading a TCX or GPX file by simply uploading it to the clock memory (by connecting it to the computer) and placing it in the Garmin/New
Yeah, that's what I tried the first time, and I don't get the route in navigation.
I have a garmin edge 820, and it works just like you told me, but not with the 735xt.
I have exported the track, in gpx and tcx, I add it in new files (it even appears inside the folder, but when I go to navigation (tracks) nothing appears, only the ones imported from garmin connect.
It's very rare, because I import them in the Fenix 3 like that without any problem. I don't have a 735XT handy right now, so I can't give you any more details.
If you can in the phoenix if it is rare.
I wanted to ask you again: What's the point in having a gps like the Forerunner 735XT with all the functions associated with its chest strap and keeping the old Garmin Podometer (the one that goes on the laces of the shoe) linked as a sensor? Can you do without it completely even on a treadmill in closed space? Thank you very much
The pedometer can always give you a slightly more accurate record of both pace and distance. Outdoors, if the signal is good, it's not necessary at all. On tape it will give you much more accurate data.
Good morning, Eduardo,
What a great article and what a great analysis you've done! Congratulations on your work and your blog!
I also just got my garmin 735XT and found a few features I didn't like about my previous Garmin 410 from over 4 years ago...
The first feature that I use almost every day is the Virtual Partner, in the 410 I could put any value of rhythm, but in the 735XT I can only put multiple values of 5, for example... 4:30, 4:35, :4:40... when I would like to porner 4:32 or 4:37 it is impossible... The same happens with the distances, if I want to do an intervallic training of series of 120m I cannot... it only leaves me or of 100 or of 150, of 50 in 50... I suppose that from the web something more can be specified but good... What more matters to me would be the rhythm of the virtual partner... do you have some idea of if there is going to be some update that solves these problems or some way to be able to choose the wished rhythm/distance as it could do with the 410?
Finally, with the 410 I could define a training by distance and that the training will stop when I get that goal, instead, with the 735XT, I do a training by distance, and when I get to the goal, it doesn't stop atomatically having to do it... do you know Eduardo something about this subject?
Thank you so much for everything!
Neither will change. Now the instantaneous rate is in multiples of 5, to avoid a lot of fluctuations. In the 410 it was filtered because it had no GPS record per second, so it averaged 4-5 seconds and therefore did show 4:32
Hello again Eduardo!
I have already bought the edge 1000, it will arrive soon and to complete it, as I told you before, I am looking for something that will measure my wrist pulse to train in the gym, run and swim in open water.
You recommended this 735XT to me and I read your analysis, very good and complete as always, the only one but that I find it is the altitude issue, it was not clear to me.
Can I see the altitude while I'm training? Even if it's not as accurate as if it had a barometer.
I had the Polar M400 and the data was pretty reliable and it didn't have a barometer either, is it something similar?
Thank you very much in advance.
Yes, in general terms it will be something similar to what the Polar offers.
You will be able to put a data with the current elevation, but not accumulated meters.
Remember that in the 735XT the optical sensor cannot be used for swimming, to have FC under water you need an HRM-Swim or HRM-Tri sensor.
I knew about the sensor in the water and I don't care, but the fact that I can't put the accumulated meters in the water bothers me, so I remember to put them in the polar.
Congratulations on the review, the most comprehensive I've found.
If I have no misunderstanding with this garmin, as it happens with the 520,100 and I think 820, it has the option of strava live segments but you don't comment it in the review. You don't comment it because I'm not wrong and it doesn't have it or because you don't use it?
Greetings and thank you!
The Strava segments option was added via an update at a later date. At the time of the test it was not yet available.
Anyway, here you can see all the details: https://www.correrunamaraton.com/garmin-lanza-los-segmentos-vivo-forerunner-735xt/
Excellent that you're sharing that data with us. I'm undecided between 735 and 920. Could you guide me through that please?
Unless you do a lot of cycling and want altitude data on the road, I personally like the 735XT better.
First of all, your analyses are very good and I have read a couple of them and they are very complete!
I'm thinking of buying this watch and the VIVOACTIVE HR. I plan to use it for running (mainly) and swimming in open water (in summer) and in the pool (in winter) , but my theme is the altimeter of the 735Xt, because where I do my training there are many ups and downs (being an area of small mountains). It will be necessary the altimeter of the VIVOACTIVE HR? sacrificing the swimming in open water with which it has the 735XT .
Thank you very much!
The altimeter is useful DURING the activity, to show accumulated meters and actual altitude. When analyzing, in Garmin Connect you will have mapping data, so the data from the 735XT will be sufficient.
Personally I don't do much mountain, so the accumulated meters are more useful for cycling, I think that for your use the 735XT is a better option.
Thank you, Eduardo,
Finally, I saw your article on the 935. Your opinion is the same if you compare the 735 with the 935?
Which one would you recommend me to buy?
If the price difference is not an impediment, the 935 is superior in many ways.
The difference is about 200€, the improvement is in many aspects, but it is not "abysmal". Basically, if your budget can reach the price of the 935, it will leave you totally satisfied.
In fact I am already convinced that it is the watch that best suits my father but I still do not see, how is it used for biking or spinning in the room? I am not clear how it is configured for individual sessions. I practice paddle tb what activity I would have to put to see results. Thank you
For spinning simply indoor cycling.
Padel will not have a correct distance record, so I recommend any profile with GPS off where the tracking you do is exclusively heart rate.
Yes, perfect, thank you very much, but if in spinning (indoor bike) in room, the only parameter that gives is time, it is not an excessively expensive timer. On the other hand, that would need, use tape to obtain then more data ... A hug and thanks for your ratings
You wouldn't need tape because the optical sensor provides you with heart rate data. For more data, the spinning bike should already have sensors.
And if I use it to walk, does it have a GPS option so that it indicates the route I have taken in order to repeat it?
Yes, it is possible to navigate on past activities.
I'm clear that this is the team I'm looking for.
Now, everyone has the option to control the stairs you climb, but I think this option is not in the clock, when it is in the garmin express app.
Another doubt is that I don't do triathlon or run because I do the activities indoors (I practice swimming pool and bike or spinning mainly and sometimes tape and elliptical). To know in swimming pool heart rate I should use sensor, but I want you to give me also information for other activities, which you would recommend me of the indicated ones.
Thank you very much. Congratulations on your work.
It does not count stairs because it does not have an altimeter. For swimming pools you should use the HRM-Swim sensor, which is the specific one with memory.
Economically, if you're not going to do triathlon and running it's more favorable buy the sensor separately .
You can also buy the HRM-Tri for all the activities you do, although in the pool it is not the most comfortable one the other one is practically impossible to use in everything else.
Here you can see the difference between the two: https://www.correrunamaraton.com/garmin-hrm-tri-hrm-swim-2/
Hi, I just received my new 735 xt. I have read all your test, as it clarifies and helps to understand the operation of the clock. I imagine that with the use, I will understand better some options that I have never used in other garmin models. There is one thing I do not get although I think it is well configured in the device. It is the option of vibration with sound removed when I receive a call to the mobile. That is, when I call, the call is activated on the screen of the clock, but I can not get it to vibrate. This option is interesting, as I usually have the sounds off. Can you tell me how to get it? Thanks.
If I understand what you mean, you simply have to have the vibration option turned on in System, Sounds.
Good morning, Eduardo.
Does the optical sensor on the wrist bother you?
I have tried the Spartar Tainer and the truth is that it is comfortable and the sensor is not noticeable, but it has not convinced me in swimming.
No, you can't tell at all. It's not flush with the back cover like the latest Garmin models, but you can't tell.
Thank you, Eduardo.
I'm going to try it.
The lactate data can be taken out with the normal generic garmin tape or you need the red v2?
I got this one: https://www.fitnessdigital.com/images/productos/XL/19/Garmin-premium-1.jpg
The HRM-Run sensors are required for advanced stroke metrics (ground contact time, etc.).
I take up the question of my colleague, with the question of FR-25, would it also be valid for the calculation of lactate?
Thank you very much for your analysis, very good and easy for those of us who get lost with so many models and features
Yes, it would also be valid
Thank you very much for your response and speed.
It's going to fall for sure 🙂
Remember to buy it through the links on the page, so you will be helping its maintenance 😉.
How does this 735 behave in gyms?
Besides running, biking and swimming, I'll use it mostly for gym, crossfit, treadmill. Will it go well?
Greetings and thanks in advance
Yes, perfectly. For crossfit I would use the chest pulse sensor, but keep in mind that in case of sudden movements and very fast intensity changes neither the optical nor the chest sensor will be accurate.
Good morning, Eduardo.
This watch is too complex and too expensive for my daughter. She mainly works out at the gym (specific classes like bike or zumba ...) and then she likes to go out every x time to walk.
I'm looking for something simple but useful. I don't care about watches or bracelets. What do you recommend? And tell me if you connect with black friday because now might be the time to buy it. Thank you very much.
If you do not need to use frequent route following a good option is the Vivoactive HR, it is a very good model for use in the gym. I left very good offers today in the Black Friday article.
I only find second-hand prices and not very cheap. You might look at it wrong
You have it at the top of the Amazon section, it's from Germany. This is the direct link: https://www.amazon.de/Garmin-Forerunner-735xt-Schwarz-Grau/dp/B01DWIY39A/ref=as_li_ss_tl?ie=UTF8&language=en_GB&qid=1511161235&s=sports&sr=1-5&linkCode=ll1&tag=c1mde-21&linkId=1dfe0d321e6aee80fb4a35689c81434d
But you didn't tell me for my daughter the live one he? I think I've messed you up by asking you inside this Post
You're right, I didn't follow the thread of the conversation. Keep an eye on the list of offers because I'm sure it will be available again
Indeed, he came back: http://amzn.to/2hP3tVl
Garmin 735xt or Polar V800?
I like the 735XT a little bit better, it has more features. The downside is the materials, a lot of plastic. at the price the V800 is today I would doubt it quite a bit... At that price and with the new H10 sensor it's a really interesting offer.
It's because of today's offer from Polar that you shouldn't do it. I think it's a good choice. What would you do?
It's because of today's offer from Polar that you shouldn't do it. I think it's a good choice. What would you do?
In terms of training possibilities they are very similar. In Polar you can limit that it is only compatible with Bluetooth sensors, thinking especially about power meters (although most of them are starting to be dual).
Garmin is far better as a smart watch, without of course getting to an Apple Watch or Android Wear.
As an interesting offer, clearly the Polar because it also adds the pulse sensor that serves for swimming (you have to pay separately at Garmin), and being a triathlon watch is something to appreciate.
Looking only at the price without caring about anything else, I would opt for the Polar. From there on, personal issues come into play that only you can determine.
In my case I would use it especially to train for triathlon: running, spinning, swimming.... Because then, I have seen that the fénix 3 hr also has a good offer would it be a better option than the v800?
Greetings and thank you very much!
Of the three, it is the most capable and undoubtedly the best in almost every respect (the 735XT has the latest Connect iQ and Strava segments), but it is considerably larger.
I bought the Polar V800. Thanks a lot for your help!
Congratulations for the page, very exhaustive your analysis (even too much hahaha). My doubt is between this one (the 735) or the Suunto Spartan Sport HR that with the tape now more or less leave for the same price. The truth is that wearing a tape or a pulse on the wrist does not matter to me, what is important for me are the interval training, farklets, ... Basically I run and do some mountain biking, swimming I do not want to go near a pool unless it is in summer to cool down. Thank you very much in advance
Then you will appreciate the more accurate data from a chest pulse sensor, both in Garmin and Suunto. For price, including the sensor, Suunto is more beneficial (Here are the best pricesIn Germany cheaper than in Spain), which I think you're going to be quite satisfied with.
Hi, I am doubting between the fr 235 and the 750xt, what differences they have from each other and how much you would recommend it, I would practically use it for running, thanks a greeting.
Clearly the 735XT is better at everythingMore sports, more complete in cycling, route navigation, with more possibilities in terms of Connect IQ...
Hello, I started with swimming this year and some triathlon, what I do more or what I spend more time is the mountain bike, then run and swim last (in see if I do because I live on the coast). I am in doubt between the 735xt and 920xt, but because I found a 920 100 euros more economical than the 735XT. What do you recommend? for daily use I spent the Forerruner 35 I have and that has been left short, but since I give the quality output as I go to one of these two.
I do not have any EDGE for the bike, well if a Touring but only use it when I load routes that I do not know to guide me because it is the simplest and only serves for that.
Thank you. I look forward to your opinion.
In basic use both will offer you the same, and what you lose with one you gain with the other and vice versa. The main absence in the 735XT is the barometric altimeter, which is the only thing that would make me hesitate between both models since the 920XT does have it. For everything else the 735XT is superior in all other aspects.
Hello Eduardo, before I had a 735xt but I changed it for a 935, the case is that with the 735 in the navigation when I introduced a track or followed some activadadad it warned me of the turns with beeps and a screen and in the 935 I only see a little arrow that goes pretty "crazy" as indicating the course that I should go. Have you removed this feature of warning of turn in the 935 or you have to activate some option in configuration? thank you.
hello i had a 735xt but i changed it to the 935. in the 735xt when i entered a track or followed a route in navigation i was warned with turn instructions with a screen and sound and beeps. in the 935 all i see is an arrow that goes a little crazy and doesn't warn of anything. have they removed that option or do you have to configure it somehow to get it out? thanks and greetings,
No, the 935 has full navigation just like the 735XT, if you activate a route you must be shown a screen with all the directions.
I'm very torn between this Garmin and the suunto spartan training wrist.
I don't want to buy a chest strap and I want it to be as accurate as possible in terms of heart rate for cycling and running. I'm not interested in the barometric altimeter, but I do like the fact that I can train my technique in the pool (I don't swim very well yet, but I would like to include it in my training).
I hope you can shed some light on this matter and give me a hand! Thanks anyway
The pulse sensor is very similar in both cases: quite good in racing, very bad in cycling. In basic performance they are similar, although in more advanced performance the Garmin offers more than just the Suunto. But it is already a personal decision and depends a lot on your particular tastes. Either one will meet the requirements correctly.
I just received this gift (just the watch) and came to give it to your site to find out what and how about this 735xt.
I have a similar question: To have all the measurements (running dynamics, VO2 and all those you explain and that the chest band is necessary) which band do I need? do I only need one of them?
I have seen that there is the classic HRM band, there is the hrm-run and the hrm-tri (I am not interested in the swimming band, although I do swim and plan to do a triathlon).
since each one of them has a different price and I don't want to spend on something that I don't have enough of... or this one.
You need HRM-Run or HRM-Tri. The difference is the memory of the second one.
Thank you very much!
Well, now I understand why it's convenient to have a package deal. Sure, as long as you need to get all the data out.
I have just bought the 735xt and I have gone out a couple of times and the rhythm always shows me 5 in 5 seconds. Can it be modified or is it a malfunction? That is to say, I go at 4:20 or 4:25 min/km. On the other hand, the average rhythm shows values of 4:23.
Thank you for your answer.
No, it works like this, the instantaneous rate is at multiples of 5 so that there is not too much variation in the information.
Hello there, a spectacular analysis. I only have one question left. You can follow a route already made or downloaded from Wikiloc entered as a route by the Garmin Connect. I have the 310 of and if it does. Thank you
Yes, of course. In fact if you are a paying user you could download them directly to the clock with the Connect IQ application: https://apps.garmin.com/es-CL/apps/54505088-813d-4700-afea-a3105366ec6b
Hi Eduardo, I had some doubts between the garmin 735 and the 935, in the end I bought the 735. I'm not much of a statistician and the only thing that interests me is if the 735 indicates the accumulated unevenness during the training since I practice mainly trail. I know that it doesn't have a barometric altimeter and it is by GPS and the measurement is not so exact.
Hi Pako, do you have a data field on the screen to display during the activity the accumulated elevation gain? i just returned a forerunner 45 because of the absence of this data, which only podías display at the end of the activity, and often I go trail running with elevation target. thanks!
If you want to have accumulated ascent data during a workout you will have to buy a watch with a barometric altimeter. Here are all the details: https://www.correrunamaraton.com/gps-altimetro-barometrico/
Grandísima explained, thanks for your time, a doubt, a few days ago I read on another website, that the dynamics of racing in this clock did not need the tape hrm, run swin or tri. that with only the clock mediate the time of contact on the ground, the length of stride, the vertical lift. This is so, because in your article I thought I understood that it would not be so. Thanks, a greeting.
Thank you Michelangelo
No, for advanced metrics you need an external sensor, with only the clock not showing it.
With the prices of Black Friday I can't decide whether to invest in this watch, which I see as very complete for what I'm going to use it for, but it's already a few years old, or the Polar Vantage M, which is something that doesn't convince me.
Which one would you recommend?
Thank you very much.
You can see the recommendation guide here: https://www.correrunamaraton.com/mejor-reloj-gps-invierno-2019/
I personally like the Vantage M better, especially if you're going to take advantage of the rest metrics.
Excellent review. I'm looking to get the 735XT with the current discount but I have a query since I'm looking for a watch with gpx route navigation. Regarding the navigation with early turn warning, it seems that you indicate that it is thanks to the routes created with Garmin Connect. If I download them from Wikiloc does not have this option? I think the sea of interesting. The 245 has also dropped in price and I have a mess that I do not know which to buy. It will be my first smartwach so I do not think I have to go for a Phoenix first since I started running this year. Thank you very much in advance.
Thank you, David.
Currently the offer of the 735XT has ended. Here you have the constant update of all offers in Europe: https://www.correrunamaraton.com/black-friday-deporte-2019/
Everything depends on how the path is created and the data that Wikiloc adds. It's been a while since I tried a watch with simple navigation with Wikiloc's paths (now everything comes with maps).
Indeed, if you are starting out it is not a good idea to go to an expensive watch, it is better to start slowly. Take a look at the recommendation guidewhich is updated a week ago.
As for FR245, this is where it's cheapest right now.
I'm thinking of buying it but I don't want a 4 year old watch that can quickly become outdated, is there a new 2019 version?
Thank you very much for your work.
Yes, for triathlon there is the 935, the 945... this year Garmin will also release a direct replacement for the 735XT. Barring a one-off offer, I wouldn't buy the 735XT at the price it is at today.
Good afternoon, very good article!
I for my part see that the problem is not the watch itself, but the software that gives us Garmin. In my watch Garmin 5 the battery life always varies between 12 - 14 days as advertised and promised by the brand. However, the latest updates (the current 126.96.36.199.0) leave me with a battery performance of 9 days max. 10.
It is worth noting that I did 3 tests just using watch without apps and connections enabled and they do not reach 14 days.
I spoke with the Garmin service and they said to send them the watch because they have to review it, which I have flatly refused since it was clear that the consumption has changed since the last 3 updates.
To give you an idea, it consumes the first 24% in the first two days of use.
How can it be that they offer such a poor service? Shouldn't we, the users, do something against this misleading sale? I want you to know that if a company offers a product that does not comply with what is mentioned in the advertisements or in the sales pitches, it is FRAUD / MISLEADING SALES.
It is a leading brand in this area and its commercial policies should be closely scrutinized. Lest it is happening the same thing that Apple did by slowing down their old equipment from the software (punishable fact and case that was confirmed having to pay millions of dollars in fines).
I would like to know your opinions and see if between all podemos do something. I have access to some means to spread our concern, if anyone offers any more, welcome.
Thank you very much!
Good afternoon, I am thinking of buying between this model and the Garmin 45, taking into account that my main sport is running and that there is today 50 € of difference favorable to the 45, my doubt is because the 735 I see it as it may be outdated. Which one would you recommend me between these two? Thanks in advance
If the only thing you are going to do is running the 45 seems more interesting. More modern, with Sony chipset and better materials. Only if you were going to swim or do triathlon I would recommend the 735XT.
Good morning, I have a Garmin 735xt and when I finish a workout in the Training Effect it never shows me Anaerobic or Exercise Load.
I reset it a few times and nothing.
If you can tell me anything I would appreciate it.
The Garmin 735 does not support training metrics.
I have received several 'updates' for the forerunner 735xt. Although it is still marking the same version I have seen that the trackback and performance condition has disappeared.
Do you have any idea what's going on? Garmin reduces the functions of its older watches?
All the options should stay in the same place, I haven't checked the 735XT in a while so I don't know if there have been any changes to the menu structure.
