I have recorded a trail race on my Forerunner 945 but forgot to stop it at the finish line. It is about 30 minutes too long. I trimmed the activity on the Connect website using my time from the race results. I then checked the result: everything was fine except for the elevation gain that was higher than in the original activity! The original activity had an elevation gain of 3600m (in line with the race description) whereas the trimmed activity has an elevation gain of 3900m. Looking at the elevation profile I don’t see any visible issue but the total elevation gain is wrong. After reverting to the original I tried the same operation on the IOS app with the same result.
Anybody with a similar issue? Any advice?
Regards
