I have been running for the last two weeks with my Forerunner 220 GPS watch. I was wondering how accurate this watch is to make sure I'm doing proper training.

Garmin would say "very accurate!" A GPS equipment engineer would probably laugh.
I spend part of my time mapping things using GIS, so I "know."
Don't get transfixed on this. If you want accuracy, use a stopwatch.
