Mapmyrun is $h1t. I went on Saturday for a long run (28-29km) and it was too much for it. Again. At first it went fine but when it got a little cloudy and it started raining the measuring went berserk. My pace jumped from less then 6 minutes per km to 8. 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
