We knew these models were around the corner. In fact, there have already been leaks on social networks over the past few weeks, and today Garmin has finally made it official.

They were the only models left to be renewed in the catalogue offered by the Americans, especially in terms of offering Connect IQ in all of them. Now, except for the most basic models (Forerunner 25 and Edge 20/25), the application platform is present in the rest of the campus.

Before going into detail on each of them I will make a brief summary of where they are in the range.

Garmin Forerunner 230 - Natural substitute for the previous one Forerunner 220It is located in the mid-range, a category that reigned comfortably until the arrival of the Polar M400.

Garmin Forerunner 235 - Replaces the "old" one Forerunner 225 (note the irony) As with the 220/225, the difference from the 230 is an integrated optical pulse sensor (with surprise).

Garmin Forerunner 630 - Arrived to replace the Forerunner 620The top-of-the-line model of the corridor-oriented watches.

Once you're clear on which range each one is in, we'll see what new features they bring. There are some common ones, such as the adoption of modern technologies that we could expect in their renewal (activity monitor, mobile notifications, Connect IQ support, larger and better screen). But there are some new features in all models, both features that were previously only present in the high-end and now move to the mid-range, and new functions.

Garmin Forerunner 230

To make it faster, first I leave you with a list of features that were previously exclusive to the high range and now also reach the medium range (to the Forerunner 230 and Forerunner 235), that is, features exclusive to the FR620 (and Fenix 3 and 920xt) that now reach these models:

  • VO2Max estimation
  • Race predictor
  • Training Effect
  • Recovery advisor
  • Specific application for cycling (TOGETHER!)
  • 4 data per screen (instead of 3)

These features are purely software, algorithms from the company FirstBeat that Garmin reserved for its top range and that now we see going down a couple of steps. And of course the addition of the specific mode for cycling, something that we were asking for (if only for comfort) and that will also come with support for speed/cadence sensor.

The following are the specific new items in this range

  • Activity monitor
  • Smart notifications from the phone
  • Support for Connect IQ
  • Estimated time to completion (something that could be installed from Connect IQ)
  • Data per second recording (previously the recording was exclusively intelligent, in variable time)
  • GLONASS Support
  • Heart rate graphic data page (the one that Forerunner 225 premiered)
  • Music control on your phone
  • Audible warnings (via phone, not clock)

The screen is now much larger (almost 50%) but without increasing the size or thickness of the clock. Both measurements and weight remain virtually unchanged, but what has been reduced is the frame of the screen, giving way to a display that takes on greater importance in the front of the clock, with considerably more contrast than the one offered by the Forerunner 220.

The autonomy also sees a significant renewal, reaching up to 16 hours in the 230 and 11 hours in the 235 with optical pulse sensor.

With this renovation, the Forerunner 23rd is located in the same place where the Forerunner 620The new catalogue is a new version of the original one, adding specific features of the high range along with other basic features that were obvious to come in the catalogue.

Garmin Forerunner 235.

The full review is now complete, so if you're interested in all the details of the Garmin Forerunner 235, I recommend reading the full review by clicking here.

The Garmin Forerunner 235 offers essentially the same functionality as the Forerunner 230, but with an optical pulse sensor on the wrist. Forerunner 225Garmin has decided to create its own technology.

Garmin Forerunner 235 - Sensor

I find this move quite logical. My opinion regarding the Forerunner 225 It has always been a clock that has served as a market analysis, to check what the acceptance of such a clock would be among the general public. In this way they have been able to assess whether their potential customers are willing to pay a premium for having this technology, but without taking risks from the beginning. So they created a clock in which they hardly had to invest in R&D and launched it on the market.

What is surprising is the speed with which the FR235 is being launched on the market. Those of you who bought the FR225 a short time ago will probably not be very happy right now, seeing the new announcement. But if it has been so fast it is a clear sign that the technology is in demand and that this is what we will continue to see in the short/medium term in all watches.

We already knew that the Mio sensor would not be a problem, as it had been tested on both our own and other products, but in the case of Garmin (just like Polar's with the A360), I will think of the sensor as "unreliable" until I can prove otherwise. That is, I dare not validate the accuracy of the sensor until I thoroughly test it in the next few months, no matter how much Polar or Garmin are behind its development.

For the time being, these sensors will remain in the mid-range, since to see them in high-end watches they still have to solve the reading of the pulse variability, something that all high-end watches use for their specific function algorithms. But work is already underway and important steps are being taken to achieve this.

In fact, in Forerunner 235 it is necessary to connect a pulse sensor by ANT+ if we want to have estimated VO2Max data, precisely because the sensor cannot make the reading of the pulse variability.

The optical sensor isn't the only new feature. Forerunner 235 will also allow you to relay the pulse data from the optical sensor via ANT+, meaning you can use Forerunner 235 on your wrist and have it transmit your pulse to other devices, such as a Garmin Edge on the handlebars of your bike (or send it to a phone or other ANT+ compatible device).

And just like Fitbit with the Charge HR and arises. (and unlike Polar), the watch will constantly use the optical sensor to track the pulse and then synchronize the data with Garmin Connect.

Garmin Forerunner 630.

The full review is now complete, so if you're interested in all the details of the Garmin Forerunner 630, I recommend reading the full review by clicking here.

Garmin Forerunner 630

If the Forerunner 230 and Forerunner 235 have received all the benefits that the Forerunner 620Firstly, these are the logical things we could expect from the renovation, similar to what we saw in Forerunner 230:

  • Activity monitor
  • Smart notifications from the phone
  • Support for Connect IQ
  • Estimated time to completion (something that could be installed from Connect IQ)
  • GLONASS Support
  • Heart rate graphic data page (the one that Forerunner 225 premiered)
  • Music control on your phone
  • Audible warnings (via phone, not clock)
  • Metronome function

The following are the most important new features for the platform, some of them seen for the first time in this FR630

  • Extended Running Dynamics with support for stride length, vertical oscillation ratio and ground contact time balance
  • Determination of lactate threshold
  • Stress level measurement application
  • Basic navigation
  • Possibility to use UltraTrac mode

As with the Forerunner 230 and 235, the display is now significantly larger, and in the case of the 630 it is still touch-sensitive. The range increases to 16 hours of continuous GPS use. Of course it is supported by Connect IQ applications, smart notifications and activity monitoring. Also the metronome function, which was introduced in the Forerunner 920xt and that we've been seeing it incorporated into the other later models.

But here are the main new features. Firstly, Running Dynamics now offers more functionality. It does not need a new pulse sensor, as it is still the same HRM-Run that was released with FR620. But now new metrics are added:

  • Stride length: It doesn't need much explanation, just the length of each of your strides.
  • Vertical Oscillation Ratio: Previously, the vertical oscillation was an absolute number as such, the usefulness of which was not very clear, mainly because it depends on many other factors, such as the height of the individual in question. Now the length of the stride will be taken into account to give a value more in line with reality and thus be able to assess whether our vertical movement is excessive and we are wasting energy in moving up and down, instead of moving forward.
  • Ground contact balance: It will show the balance between left and right foot, that is, if your right foot spends more time in contact with the ground or vice versa, creating an unbalanced way of running, as if you were limping.

Garmin Forerunner 630

The next novelty is the lactate threshold test. I am very curious to try it, because I am not very clear how they can determine this value simply by heart rate values, especially since until the advent of BSX Insight, the only way to check it reliably was with a puncture and blood tests from time to time.

For those of you who do not know what the lactate threshold is, it is the turning point between the rhythm that we can maintain for a long time and the rhythm that if we maintain we will not be able to endure. When we run, we produce lactic acid, which stays in the muscles and it is our own body that takes care of cleaning it. The lactate threshold is the point at which our body is not able to eliminate that acid from the muscle fibers, leading us to fatigue.

So the question is how Garmin can determine this value simply through an algorithm, and what value it will give us. My guess will be that it will indicate heart rate values from which our fatigue will increase. Another thing to look out for in order to do the full analysis.

Price and availability for Garmin Forerunner 230, 235 and 630

Well, that's all very nice, but when will they be available? Well, there's no specific date, but Garmin says they will be available in the fourth quarter of 2015, which is from the minute you read these lines until December 31 at 11:59 p.m. But based on the experience of previous launches, I would expect them in January or February of next year, especially with the chaos that occurs when a new product comes to market.

There will be a wide variety of colours to choose from, as detailed below:

Garmin Forerunner 230Available in black and white, purple and white, black and yellow

Garmin Forerunner 230 - Colors

Garmin Forerunner 235Available in black and red, black and grey, black and light blue

Garmin Forerunner 235 - Colors

Garmin Forerunner 630Available in black and navy blue

Garmin Forerunner 630 - Colors

And as for prices, which is the most important, they will be the following:

Garmin FR230Clock only 249 ?, in pack with pulse sensor 299 ?

Garmin FR235: 349€

Garmin FR630Clock only 399 ?, in pack with pulse sensor 449 ?

My opinion

The renewal of the range was quite expected, as both the 220 and the 620 had been on the market for quite some time. But it was no less surprising. I think Garmin has taken a big step, especially in the case of the Forerunner 230, as it has put it back at the top of the mid-range. Polar had eaten their toast with the M400, something you have probably already seen in the sales level. The M400 offered a higher level of features at a lower price, especially at the level of support for other sports (mainly cycling), which Garmin has finally solved by giving the watch a new specific mode. It also receives all the features that were previously reserved for the top range.

The Forerunner 235 brings the most important new feature, with its optical pulse sensor. It's a major leap forward for Garmin, and it's crucial that they get it right. They've already taken their first step with the Forerunner 225And having determined the real interest in this type of sensor (and assessed how much more the public is willing to pay for it), they have set about creating their own technology - something that will not only save them costs, but also give them complete control over what the sensor can and cannot do.

Finally, the 630 brings important new features, not only for its category but globally to the entire Garmin range. Forerunner 620 Garmin continues to launch new features in its high-end model, with important announcements such as the lactate threshold test and new metrics for running dynamics.

I've been surrounded by electronic devices of all kinds for more than 25 years. Using them, testing them, taking them apart and dissecting them. Long distance triathlete: I swim, run and cycle for a long time. Maybe too much.

  1. We know if the news of 620 will reach the Phoenix 3, that of the milky threshold, the sancada left right, and other news. Or better yet, which will arrive and which won't. And when, we will have to wait for 620 or we will have it before.
    Greetings

    1. At the moment Garmin has not made a statement. If I had to bet, I'd say they will eventually arrive, but not before the 630 goes on sale and spend some time "enjoying" its unique features.

      1. Hi, I would like to ask if it is known if the fenix 3 or its version 4 will carry the optical pulse sensor, and if so, when? thank you!

  2. A pleasure to read the whole article, super interesting, just
    I have a question that I'm not clear about what I put below written by you, Did you get drunk
    than to buy the ANT+ sensor to know the data of the VO2MAX in the 235?

    In fact, on Forerunner 235, you need to connect a pulse sensor
    by ANT+ if we want to have estimated VO2Max data, precisely
    because the sensor can't read the pulse variability.

    1. Indeed, the calculation (estimation, rather) of the VO2max requires pulse variability data, which is currently not possible to obtain with current optical sensors.

      There is no doubt that this will be achieved in the future, perhaps with these sensors or with a new generation, but for the moment it is not possible.

      But thanks to the possibility of connecting the external sensor, it would be possible to obtain the data that way.

      1. But not 230 if the estimate is correct, as it says in the characteristics.
        I was looking at 225 to get him now, but I'll wait and shuffle which one to get, either the wrist optic pulse or the VO2max estimate.

      2. But not 230 if the estimate is correct, as it says in the characteristics.
        There was
        looking at the 225 to get it now, but I will wait for these new heart rate monitors that are almost no longer mid-range and I will consider which one to get, either the optical pulse on the wrist or the VO2max estimation.

      3. But not 230 if the estimate is correct, as it says in the characteristics.
        I was looking at 225 to get him now, but I'll wait for these new
        I'll be considering which one to get and which one to take or which one to buy.
        the optical pulse at the wrist or the VO2max estimation.

          1. I read this, it means that you can have the VO2 MAX with the 235 without the HR? band already taken out of here:

            http://www.dcrainmaker.com/2015/10/garmin-fr230-fr235-fr630.html

            We see some of the advanced features previously only seen on the FR620, moving their way up to the FR230/235. For example, the VO2max values are now found on the FR230/235. Note that for VO2max tests although you do not need to have a traditional heart rate band it is combined to the FR235, as it is not able to take advantage of the optical sensor for that test (common due to the lack of precision of the heart rate variability in the optical sensors). Update: It seems that they are allowing this with native optical sensor.

            Garmin-FR230-Recovery-Advisor

            Similarly, we see Training Effect and Recovery Advisor functionality moved to the FR230 / FR235 as well. Note that Training Effect also requires a HR strap with the FR235, but the Recovery Advisor can take advantage of the optical sensor. And we get Race Quiniela, which spits out better guesses about how hot a race is based on the VO2max figures (i.e. shows running at 10K 36min).

          2. Ah! well, how nice if you no longer need to connect a pulse sensor!
            by ANT+ if you already get those values together with the estimation time, because I forget about the band on the chest, as at the beginning you couldn't. Thank you very much.

  3. Too bad it doesn't include a wrist sensor like the 235.
    Will there be a 635 that does?
    For those of us who don't need exhaustive HR accuracy, wearing it on the wrist is much more comfortable than wearing a band.

    1. Note that advanced functionality depends on external sensors, both the HRM-Run pulse sensor and the HRM-Run itself, to measure pulse variability and provide other information.

      Actually, the 630 without the HRM-Run sensor would be left with virtually the same performance as the 230.

  4. Hello, do you know if the price of 230 with the band, is the one you can see the V02MAX? Or should we buy a different one?

  5. What is pulse variability and what is it for? what is vo2max? that pulse variability function is only useful for vo2max data? thanks for your answer.

  6. Can the 235's wrist pulse sensor be turned off to save battery power?? if I use the 235 with a chest strap the battery lasts as long as the 230?

  7. Morning,
    The price of 230? is not very high, the 220 is right now at 165? and the Polar M400 at about 175? in amazon. 299? is almost double!

    1. Please note that these are RRP prices. In the recommended price, the 220 with sensor is at 249 and the M400 at 200.

      It is clear that on the first day of sale the price will be the recommended one, but as it has happened with the 220 and M400 (and with all the other models), it will go down to very similar ranges.

  8. Hello, there is the possibility of tracking routes , imported from some platform ( Wikiloc , Estrada , etc...) , in the garmin 230-235 models.
    Greetings and thanks

  9. They really did a number on those of us who bought in July on 225. Is it known if there could be any compensation or renewal plan to move us to 235?

    1. Personally, I think it was a rather erratic move on the part of Garmin, but it was partly caused by the good acceptance that the 225 has had in the market. They saw that the optical sensor was in demand, and so they did not want to wait any longer to present its replacement.

      I doubt Garmin will contemplate any action for those of you who have bought the 225 recently.

      Please, don't forget to vote for the Blog Awards.

      1. Thank you, Eduardo. I'll still write to them to see if there's any compensation. If that's what I'm telling you for publication. Best regards.

  10. Hi, Eduardo.
    On the 230, can you have both a heart rate monitor and a speed/cadence sensor connected (and recording), or does it only support a single connection?

    A salute.

    1. No problem. ANT+ supports up to 8 concurrent connections (of different profiles), so there is no problem in connecting several sensors simultaneously

      1. Great, then. Thank you very much.

        From what I see on Twitter, there are already stores in the US that have it (@TriNRunLaf / @FFSMontgomery).

        I hope it won't take long to get to Europe / Spain.

        A salute again.

  11. which model do you recommend for running? the polar v800 or the new garmin 230?

    I'm just going to practice the sport of running (now called running)
    If I didn't need any mountain track, which one would you advise me?
    Greetings and thanks for the website.

    1. Except for the running dynamics, it's about the same height as the 620, and it's one of the strongest options right now. The V800 would recommend it if you're into triathlon or frequent swim training, but as a race watch, the 230 has everything you need with great performance.

  12. Hi, Eduardo,
    I'm very interested in the Forerunner 230, I've already looked at several pages that have discounts but I wanted to ask you: Do you see a madness in buying it from me as soon as it's on the market, because of possible software problems or something like that?
    Do you think I should wait for me, or can I correct any mistakes with future updates? I say this because black friday is coming and it will have to be approved...
    Thank you!

    1. Hello, Antonio.

      The test will, I hope, be finished during December. I am expecting to receive a unit of the 235, since the test will be a joint one of both models (230/235). However, I have already been testing the 230 for a week.
      So far I like what I'm seeing. Quite a lot. I've seen some "weird" things like the automatic change of meters for miles, but I'm not sure if it was a problem of the watch or my problem without noticing it. Otherwise it has a pretty solid performance.
      You can keep an eye out to the article on Black FridayI'm sure that on the big day, Friday, there will be some offers that can be applied to FR230. In addition, buying through the links I provide will help maintain the site.

      1. Okay, so I'll wait to read your proof or see if there's a good deal. For now the cheapest I've seen is 230, see if it can come out any better. Haha
        Thank you.

      2. Hello again!
        In the end I took advantage of an offer and bought the forerunner 230 with a band for 224 Euros. I think that's an unbeatable price!! The problem is that I have to wait for it to arrive to them and they send it to me and they say that I will receive it between December 14-18 and I'm looking forward to it.
        But just one question, as you're testing the 230 model, have you seen any significant flaws in it?
        and another question, do you know if from the Garmin IQ page you can download any application that could count the lengths in pool or for this model you can not make applications that meet that objective?
        Greetings and thank you very much!

        1. I am working on several tests right now, of course one of them is the 230 for which I already have all the data, I hope to have it ready by mid-December.

          As a possibility, it would be theoretically possible to make a Garmin Connect IQ application for swimming metrics. But Garmin won't do it and I doubt very much that there are users with the knowledge and ability to do it. And since it is not possible to monetize these applications in any way, I rule it out completely.

      3. Hi Eduardo, I've been using the 230 for 4 days now, and I checked what you said. The device changes itself to Miles, so it indicates the activity in that unit. You have to stop, go to Units and change it to KMS. The same goes for the height (it changes it to feet). Before you start the exercise you have to change it again manually. And no matter how much you synchronize with Garmin Express or Garmin Connect it doesn't stay adjusted. I imagine this will require a software update. Do you know how to report this to Garmin?. Thanks, a greeting.

        1. Yes, there is a bug right now that affects 230, 235 and 630. The problem is not in the clock firmware, but in Garmin Connect, that even if you modify this detail and save the configuration, when you come back in it is still in miles. It also happened to me with the Vivosmart HR.

          You can contact support on twitter: https://twitter.com/GarminIberiaSAT By mail: [email protected] By phone: 932754497 Or in any other country: http://www.garmin.com/us/support/contact?#fragment-3

          1. Hi guys. I got a 630 and I've been trying it out for two days to understand how it works. I had the same problem with the miles and kilometers and trying it out I found the solution (I don't know if I'll ever get out of the page and back in again...)

            You have to go to: your Garmin Connect profile + settings + display preferences + in the "units of measurement" section change "statute" to "metric".

            That's what I've done, and now he shows up in miles...

            Good luck 😉

  13. Hi Eduardo, I'm hesitating between buying the 230 or the 235. I've been running for about 4 years and several half-marathons done in 1:45:00, I want to do the jump to the marathon distance and I want to have a watch to do the training with series and changes of pace. Do you think it's worth having a watch with a pulsometer to train that test? Both models have the same features except for the pulsometer? I take this opportunity to tell you that I love your site, not only for the tests but for the training tickets and so on. Thank you.

    1. Both offer you the same, the difference is that the 235 integrates the sensor and the FR 230 is used with the sensor on the chest, otherwise the features are the same.

        1. Yes, Garmin has also included it in the version with an optical sensor. A unique case, since it is not normal to incorporate it with this type of sensor. But the truth is that we are already making good progress in obtaining HRV data with optical sensors.

  14. Hi. I see you commenting around here that you get the metric units in miles. I do too and it happens and I can't get them to show up on KM. Did you get it???? I can't get 4 display fields on the screen either, only 3...

    many thanks

    1. Configuration, system and units. From the application it is not possible, because it is always configured as miles and sometimes it is changed again.

      In the layout of the data fields you can change the way they are displayed

  15. Hello the kings are bringing me a watch and I'm hesitating between the forerunner 230 or the Suunto ambit 3 run, can you help me? Just to run.

  16. Hello Eduardo, do you think it is a mistake to buy at this point the 225? I am little more than a beginner and I have seen an offer of this model for 185 euros, the price of the others is slightly off.
    Obviously what I liked best about this model was the vibration alert and not having to wear the band.
    I don't know if, from here even a short period of time, there could be a problem in case at some point I had to resort to the technical service to solve any failure.
    Thank you very much for your attention.

    1. Naomi, I can't find anything in the 235 that would justify the almost 200 euro difference. The 225, at that price, is a round trip purchase.

      Aside from aesthetics and size, what sets 235 apart is the notifications and heart rate throughout the day.

      1. Hello Eduardo, the 225 also has the option of returning by navigation to the starting point... I thought I read that the 235 does. I'll be grateful if you confirm both the 225 and the 235. Thank you very much.

      2. Hello Eduardo, the 225 also has the option of returning by navigation to the starting point... I thought I read that the 235 does. I will be grateful if you confirm both the 225 and the 235. Thank you very much and a cordial greeting.

  17. Do you know if these wrist sensors are as accurate as the chest strap?
    On the other hand, I wanted to know if someone had used the 235 in the water and had a good pulse through his wrist, and if he was continuously being held. That's what interests me most.
    If the pulse eats it well without tape and if it goes well in the water.

    1. You can take a look at the complete test, at the beginning of the year you will have specific data of the 235. You can also look at the test of the Garmin Vivosmart HR, the sensor is the same. Or the test of Mio Link or Garmin 225, where the optical sensors are also widely discussed.

      When used in a swimming pool it is not valid. The data is totally wrong.

  18. I have a fleece from a few years ago, RS300, with a treadmill and pedometer in the shoe. I am assessing a change between Garmin 230 or the Garmin 620 that I have found to be nicer than its initial price of 399.
    I am a regular senior runner, but not very integrated in the use of the latest technologies.
    What do you think of the new Garmin 230 or the old Garmin 620?
    Thank you very much for your comments.
    Best regards.

    1. The only thing that the 620's 230 hasn't received is the touchscreen and racing dynamics. Otherwise it offers the same with a bigger, better quality screen, better Bluetooth connectivity (and related features) and activity monitor.

      I find 230 more interesting.

  19. What activity clock would you recommend for interval training?
    The problem is that so far, I have only found the Polar V800 watch that has the option to set a target for the 300m, 400m series... But this is beyond the budget I have.
    This option is very important for me, to know if I should increase or decrease the rate.
    In principle, the rest is done on the basis of time and the series on the basis of distance (including the target with time).

    After quite a while of searching, I only found that watch.

    Thank you very much.

    PS: Congratulations for the web, very complete. Reviews with rigor and seriousness.

    1. You can schedule trainings with 300 or 400 meters duration and then the rest period. Take a look at the advanced training section.

      1. What I'm looking for is a watch that has the option of setting up interval and target workouts for those workouts. So far, the ones I've seen (Garmin FR230, FR220...) don't allow for the selection of a target to warn if the speed is adequate to end the interval in the expected time.

        Can you recommend any other than the Polar V800 (which does include the option)?

        Thank you very much.

        Greetings.

        1. I don't understand you, why don't you use the Garmin training?
          You can select the interval in time or duration you want and the pace at which to do it, receiving notice if you are above or below.

          1. You may have misinterpreted what you indicated in the analysis of Garmin FR130:
            "You can define warm-up, cool-down, work and recovery periods. Each with a specific duration (in time or distance). What you can't do in this mode is specify a target for each stage (you can't indicate that your work interval is between 3:50 and 4:00 as in the image above)."

            Is it possible that you mean to set this mode on the same clock, allowing the input of targets from the web?

            Thank you very much again.

          2. Yes, that's for settings from the clock itself, but all those variables can be created in the advanced workouts you create from Garmin Connect and then synchronized to the clock

        1. It's a totally personal choice. I recommend you read the tests on both 230/235 and 630 (where I detail the differences between them) and choose.

  20. Hello:
    You point out that the 235 replaces the "old" Forerunner 225 (note the irony). As with the 220/225, the difference from the 230 is an integrated optical pulse sensor (with surprise). That's not correct. The 225 has an integrated optical pulse sensor. What I want to know is exactly what's wrong with the Forerunner 235 over the 225

  21. Good morning, I have acquired garmin 235 and I wanted to know if it is compatible with the new garmin HRM-RUN sensor, the red one.

  22. I have the 220 and I want to change it for the 235, I want to try the optical sensor, since the band on the chest causes me wounds and I always have to walk with adhesive tape and I'm tired of washing the band every day. I will notice much improvement over the 220????? I can use it for swimming????.

  23. Hello! I'm hesitating between ambit3 or forerunner 235

    I like the forerunner235 but it measures the altitude by GPS, wouldn't it be better? Is the forerunner only for running on asphalt?

    Then there is also the size, that although both are big the ambit is more...

    Which one would you recommend?

    Thank you!

    1. The Ambit3 would have to be the Vertical or the Peak, which are the ones with a barometric altimeter. The Sport doesn't.

      The 235 is more oriented to stay on the road, not that you can't get it out of the black, but it is what it is designed for.

  24. Hi! thanks to your great analysis I decided to buy a Forerruner 230 in September and I was very satisfied. a week ago I stopped using it (because I got sick and left it on my nightstand). today I put it on and the vibrator is not working, neither for the alarm nor the notifications. I reset it, turned it off, updated it, and it still doesn't work, do you know if it's a common problem, what can I do, do you recommend me some tutorial to fix it? please help. the truth is that it's almost new, and it gives me courage that it has been spoiled so soon, I take care of it from the direct water and in general it doesn't have a rough use or anything. thank you very much in advance for your answer
