Manage local ride data

Imports merge by ride start time and preserve your current recovery. Workout favorites can be exported in Workout studio. FIT exports use active ride time; paused time is omitted.

First ride? Here’s the setup.
  1. Power on your Bluetooth FTMS trainer and close Wahoo, Zwift, or any other app using it.
  2. Use Chrome or Edge on your computer. Allow Bluetooth access when prompted and select your trainer.
  3. Pick your ride and a comfortable power target. Start pedaling, then press Start ride.
  4. Use Pause for a break, or End ride to stop and save. Escape also ends the ride.

The app needs an FTMS trainer supporting your selected control mode. If your trainer isn’t listed, check its firmware in the manufacturer’s app. Ride data stays in this browser. Use FIT export for compatible activity apps, or CSV for your own analysis.
