Big discrepancy

An easy run around my local loop of 11.3km (from MapMyRun). It turns out that the Garmin measures it closer to 11.0km. That's a big difference. Not sure what to believe!

Anyway, the time was 45:22 and if I trust the Garmin that's 4:07/km pace. Feeling good and looking forward to the race on Sunday.

Hi Matt, I have found that mapmyrun always overestimates distances compared with my garmin, especially noticeable on longer runs, e.g. 1/4 of a mile on a 12-mile run, so similar proportions. I'd believe the garmin (sorry!-sat navs never lie...) plus my garmin compares spot on with AAI measured races (more evidence I think....)
