When to use it
- Your watch or bike computer ran out of battery mid-ride.
- You forgot to press start, or saved the wrong activity.
- You trained on a gym bike or treadmill without a device.
- You want your weekly hours and training load to be complete.
What’s in the file
A standard activity: a session and a lap with your totals, plus a data point every five seconds with your average speed, heart rate, power and cadence. It’s built with Garmin’s official FIT SDK and passes its integrity check.
Keep it honest
Enter what you actually did. Made-up efforts don’t make you fitter, and they make every training load number less useful, including your coach’s.
