I’ve used Firstbeat’s ATHLETE product for quite a while. It was officially unsupported nearly a year ago.
The COACH function of it was great for giving a suggestion for the desired training effect from today’s exercise based on recent performances. It still worked perfectly well enough, even though it was unsupported.
However with recent changes to the FIT file spec, FB Athlete simply does not import many FIT files for me any more. Specifically ones that allow DEVELOPER data which, for example, includes POWER DATA from the STRYD CIQ field.
It didn’t work either with swim-based cached HR data but I was prepared to struggle through that one by using the awesome (but not free) fit repair tool. That’s my go-to tool for fixing anything. It does fix pretty much anything FIT-related but I just can’t face having to manually fix a third of my workouts before importing into SportTracks.
If you are in a similar position to me then the fit repair tool will solve your problems.

My favourite kit and nutrition
- Maurten â the race nutrition trusted by elite athletes. Gels and drink mix engineered to be easy on the stomach.
- Garmin 90-degree charging adapter â the small adapter that keeps your charging cable tidy at the stem. Essential for race day.
- Garmin charging puck â the fastest and most reliable way to top up your Garmin before a session.
- Ravemen FR300 â front light that mounts directly under your Garmin or Wahoo head unit. Keeps your bars clean and your beam pointed where it matters.
- Garmin Varia RTL515 â radar rear light that alerts you to vehicles approaching from behind. Pairs with your Edge or Garmin watch.
- Stryd â the footpod that brings running power to your Garmin. The single most useful running upgrade I have made.
- Favero Assioma Pro RS2 â the power meter pedals most serious cyclists end up choosing. Accurate, easy to move between bikes.
