Polar S625X (1)

Yet another 625 question. When I finish a run, the watch might read something like, 7 miles, 49:21. But when I download the data to my PC and upload to training peaks, it’ll read 6.8 miles, 47:54. Has anyone else seen this? Why the discrepancy? I feel I’m being cheated out of padding my training log:) Any ideas? thanks.

Mine does the same thing – chops off the tail end of the session occasionally and unpredictably. I have no clue why. I have gotten in the habit of leaving the timer on during my cooldown until my HR drops to an arbitrary “recovered” level. I can still set a lap time and get the true training distance, but am not disturbed if the last minute or two of the cooldown doesn’t end up in the computer log.
