I use the map my run app to track my running - it tells me my distance/time per mile as I run then I can pull it up on my computer after my run. You can also go to the website and map out a course to get distance. The 5 mile run I did this weekend did NOT match the race route. My app said I hit 5 miles where the course had me w/ about a 1/3 mile to go. I even tried to map out the course on the map my run site and it didn't quite match either [course was longer] so I'm wondering - which is right?
Does anyone use a running app like map my run or run keeper and if so, how accurate do you find it to be? How else do you measure out your runs??
