Today I run a 5k in 17:26min, roughly 20seconds slower than my 5k prediction. It was an all out effort in Training on the track, so the race prediciton should adapt to it you would think. Paradoxically garmin increased the 10k time by over 20seconds, altthough my Vo2max decreased a little. I‘m curious if other people experienced the same and what could be the reason for it. Cheers.
