lap details?

[lnovali]

is it possible to extract the details of the laps? what parameters should i use?

[fundthmcalculus]

Which specific details are you trying to find? Lap average information (eg lap average speed)? Or lap-specific information? (eg lap-duration)

Hello, I'm sorry for delay.
For each lap, I need all lap specific informations:
lap number
lap starting time
lap duration
lap distance
lap avg speed
lap max speed
lap avg heart rate
lap max heart rate
lap avg power
lap max power
lap ascent
lap cadence
lap starting coordinates (lat;lng)
and so on...

Just in case it helps someone else, try starting with something like:

for m in fit_file.get_messages('lap'):
    print(m.get_values())
