Hello guys. Yesterday I've had a 10K race and the GPS went terribly wrong, although it was a good weather day and not many obstructions (very wide street). Of course the total time is good but I cannot analyse my performance on each km because GPS was off, so I have kms that are way too fast or way too slow. Can I somehow modify the GPS points graphically or at least can Garmin do it if I contact them and give them the correct route ?
