I know I lose pace as I add km but not like this. And by the 25 km mark it stopped working altogether. Only God knows what this crap measured so far. Maybe some of the km ran thus far have only been ran in my imagination
I’ve never had an issue with the app, other than it’s simply not as accurate as my GPS watch. Mapmyrun consistently reads my mileage too high, consequently providing an overly optimistic pace. For example, during my run last evening, when the app read 10km my GPS watch was reading only 9.5km. Doesn’t sound like much of a difference but it’s significant in that Mapmyrun resulted in an average pace of 4:53/km whereas the GPS watch I was wearing at the time read 5:04 .
From the few timed events I’ve done, the official time is always closer to what my watch reads.
