Well, just came back from an outdoor run to calibrate my foot pod for future treadmill use... Looks like it's dying!
Red = footpod, blue = gps.
I went for another run with it yesterday and it wasn't as bad as that! I had a few spikes, but the speed was ok most of the time...
Anything I can do to make it better? Is it just the battery dying? (didn't receive a warning yet.)
