I ran last night and when I uploaded my run to Garmin connect, the map shows as if I was approx 15/20miles away from where I actually was !?
I have only has my Garmin for a week.... so I am still new to all of this..... my 2 runs last week were spot on - could it possibly be because my garmin was on underneath my jacket sleeve last might ??? (I can't remember if this was how I wore it last week or not ?)
Any help/advice/comments most appreciated.... thanks :)
