Hi, unfortunately garmin does not support laps natively. I try to find an algorithm, to detect the interval laps automatically.
1. Configurations: the user can set whether he starts and ends training typically with a warm up /cool down phase (maybe this is not needed at all). Furthermore he can configure what the minimum interval pace is. This is needed as rough orientation for the lap detection algorithm.
2. A new lap is created at the beginning of the workout (that's easy)
3. A new lap is created if either the transition of a slow pace to the configured pace (maybe minus 60 seconds) is detected and vice versa.
What do you think? Any further ideas?
