I have been biking for over a year using Map My Ride, typically I ride the same route, there is a lake near my work that is 5 miles around. I typically buzz around two or three times. If I go around twice it has always logged 10.09 to 10.14 miles. This past week it has logged 9.02 to 9.21 at a slower rate.

I rode 2150 miles last year and I wanted to ride 2500 miles this year however with this 10% loss it is going to be more difficult. If anyone in San Diego sees this post I ride around Lake Miramar

Has anyone else noticed a change with their phone apps?
