Was compatible with Venu2. Any update for Venu3 ?

August 20, 2023 | Version 0.37

I would like an explanation on how to use it though. I have been using it for a while yet I still don't get it.

Hi Roy Apologies - there was an issue on 0.34 which caused starting the downloaded workout to fail on some devices - would you be able to see if your device can update to 0.35 which should resolve the issue Thanks

Good concept but doesnt download all activities from garmin. It stopped at 200 activities and year 2020... hahahaha. oldest first I guess. unusable as it doesnt understand recent history from garmin. total fail.

February 19, 2022 | Version 0.31

The best training app ever Like having a personal trainer supporting you and maybe even better

June 17, 2021 | Version 0.29

does not work since fenix 6 pro update to V 16.7.

Hi - we're very sorry to hear that. Garmin produce a wide range of devices and sometimes updates on certain devices have issues. Would you be able to drop us an email to [email protected] and we can try to investigate our end and see if there is anything we need to feed back to Garmin? Thanks

hola tengo un garmin venu y me dice que no puedo descargar entrenamientos porque no hay espacio y ya borre todas las actividades y entrenamientos desde celular y computador. y otra observacion no me sincroniza las actividades hechas con mi garmin conect hacia trainasone mil gracias quiero comprar la suscripicion antes que termine periodo de prueba.

February 11, 2021 | Version 0.29

I had hoped that the app would improve integration with Garmin and fix recent issues. However, even after the install of this app I get "activity does not contain any detailed data (e.g. velocity or heart rate..."). Trainasone is connected to Garmin Health and Garmin Training and now to the Trainasone app. Still, no further details (so no AI analysis for me anymore). Giving this a few days to see if it self-corrects. (Cannot get resolution via asking a question as I do not have a paid subscription)

Hi KC Our apologies - we encountered an issue earlier this week that caused detailed Garmin activity data to be excessively delayed. The issue has been resolved and the backlog should finish clearing shortly.

Hi Frank, Would you be able to click the "Have a question?" link on the TrainAsONE site, or send us an email to [email protected] so we can investigate this further? Thanks

I am now using Trainasone for a year. Having a training specifically suited to my own actual fitness level makes a big difference. I am now enjoying every run. In the past I had running injuries as a result of following a running schedule that was created for an average person. This works so much better.

This is a very clever running tool that provides AI based running programmes. Having it sync with your Garmin is extremely handy as well.

Can't download workouts onto my Forerunner 245. Error says that the "workout download timed out".

Developer Reply
January 2, 2020, TrainAsONE

Hi, unfortunately there is an issue with the latest firmware on the Forerunner 245 and 945 that prevents widgets from directly downloading FIT workout data. This is an issue with the watch of which Garmin are aware and actively working on a fix When the widget shows "download timed out" it should show a "more info" option which has some more information on the issue - is this not showing,(or if it is would you have any suggestions as to how to make it clearer? - its sometimes quite difficult to format information for the watch display. Thanks More information on the issue is at

November 29, 2019 | Version 0.26

This is by far the best running training program that I have ever found and used. The way it customises the training based on your individual response (including missed workouts) is amazing! Love it!

Very good app love using it. But... as soon as the trial is over the free version does not support using the workout from your Watch. Had to memorise the instructions from my phone and keep an eye on my pace zones through my normal run settings. No where NO WHERE! Does it say that this feature is not apart of the free version. I’d happily pay but not in UK pound conversion. Can’t see myself persisting with the workaround to use it, to cumbersome

Hi Harra, Sorry we're not able to provide the right subscription option for you, though if you connect your TrainAsONE account to Garmin Training we can push the upcoming workouts to your Garmin Training calendar on the watch (which is available on the free TrainAsONE plan) Thanks

Great widget!! Really enjoy the training and I can see the results. In my opinion it is a lot of better than Garmin coach. Sometimes the training is short but I can see the reason behind that.... great recovery. The special trainings like intervals and thresholds are quite challenging. Also great support for the guys there!!! Thank you ! Keep up !

I love this app though I'm still frustrated that "workouts are full" bug has not been fixed. I removed all my workouts, uninstalled and reinstalled the app and it still only shows the workout without letting me do it. I'm not sure what more I can do!

Developer Reply

Garmin have assured us that they are planning to fix the workouts full issue in a future software update, but until then all we can do is ask users to clear their workout files when it hits. The best way is usually to connect the Garmin up to a computer via its charging cable, then remove everything in the GARMIN/WORKOUTS folder. If that doesn't work can you drop us an email direct to [email protected] and we'll see what we can do - thanks

Garmin released the new SDK allowing us to mark the app as 5 plus compatible a couple of days ago - we're planning on releasing a new app version which will should as as compatible later today (We're just finishing testing a new feature) Thanks

The app works great with just one caveat: It keeps adding workouts to my Forerunner 935 until storage is full. I then have to delete all the workouts manually. Not sure if this can be fixed, but definitely a bit annoying. Otherwise, works great for me and really happy to have this app

TrainAsONE is a very very good solution to build a training plan and adapt it automatically based on your performance and your real life constraint. That's the first time ever I find such a good solution on the market. The app gives a seamless experience for the runner: no need to do anything manual to get the workout details in your watch. The download works perfectly and the workout screens are clear and detailed. Thank you TrainAsONE team ! Keep up the good work !!
