About
TrainAsONE uses your running data to build a personalised training calendar
Whether following the plan, running with friends, or taking a few days off, TrainAsONE constantly adjusts your plan, maximising performance gain and minimising injury
Personal, flexible, adaptable and unique. TrainAsONE trains on your terms, guiding you every step of the way to amazing results. go.trainasone.com/garmin for more details.
We believe everyone can Train As One to have the best chance to remain health, fit and injury free - whether running for your first 5k, or competing in an Antarctic ultramarathon.
This app allows you to view your next workout, and download directly to your watch. It also can adjust settings for workouts which TrainAsONE push directly into Garmin Training for all workout capable watches.
The downloaded workout can target pace, heart rate, or a combination based on workout step type. This can be configured on your TrainAsONE profile screen or in the watch app.
Please note that Garmin only enable app download of workouts on the following watches. Workout download also requires a full TrainAsONE subscription (or free trial).
Please note: If you are running with external sensors (such as a heart rate strap or footpod) connected to your Garmin you should wait five seconds on the final watch screen before starting workouts to give them time to sync fully.
If your watch does not support automatic download (such as a Forerunner 235) you can still link TrainAsONE to Garmin Training to have workouts sent to the on watch Training calendar.
We very much welcome comments and suggestions on this app - your feedback helps us make it better. Please use the 'Contact Developer' link freely.
