Drop a ride file, watch it play back. Free, in the browser, nothing uploaded.
Monsoon Cycles, Colorado Springs · Updated August 21, 2026
Drop any .fit file from a Garmin, Wahoo, or any head unit onto this page and it plays back: the route drawn from GPS, elevation, speed, power if recorded, heart rate if recorded, on a timeline you can scrub. Everything happens in your browser. The file never leaves your computer, which is not a privacy slogan, it is how the page is built; there is no server to upload to.
For the full experience, the game turns the same file into a rideable private course: RIDE A .FIT FILE under MORE.
