I'm just back to running again aftar long absence. Tried the "run against yourself"function which apparently doesn't work perfect considering this thread
. If i understand it correct the virtual trainer is using average time, distance, speed to measure your progress which should work ok if you run at a steady pace the entire time. (which i assume most people do).
Still, would it be possible to have virtual trainer with route-waypoints? Then the watch could compare landmarks and let you know if you're ahead or behind.
