Frequently asked questions

What is a FIT file?
FIT (Flexible and Interoperable Data Transfer) is a binary format created by Garmin to store activities: position, heart rate, cadence, power, laps and the workout summary in a small file.
Which devices record FIT files?
Garmin, Coros, Wahoo, Suunto and most bike computers. Strava gives back the original .fit under Export Original when the workout was recorded in that format.
Can I see the route in 3D?
Yes. Open the same file in the PaceGrid Explorer to watch the route animated over the terrain, with pace, heart rate and elevation.
Is my file uploaded to a server?
No. Reading and converting happen in your browser; the file never leaves your computer or phone.
