I am using Endomondo by importing data from my Garmin 620. Whenever I import to Endomondo the data from a pre-planned training session the data get corrupted.
The average pace of such pre-planned sessions is identical on Garmin and Endomondo but the pace of the laps shown on Endomondo (web and app) are wrong. Typically, the pace of all laps except the last one are all much too high and the final lap is much too low (thus arriving at the correvt average.
Can anyone explain?
