I just did a run this morning with 5 PRs including 45 miles in 2:10, a half marathon in under an hour, a mile in 55 seconds, etc. etc. It showed that I ran from Meriden CT to the Bronx, when in fact my loop is in Westchester County.
It was my usual 12 mile run and I corrected the mileage at the end (but of course it messed up my data in Training Peaks, Strava, etc.). I had a Fenix 5 for three years and this never happened, even when I had to start a run before it could find a GPS signal. This is probably my 10th run with the 945 and I found it odd. I sync the watch probably daily or every other day and I turned it off and on again.
I will do another run before I really consider it a problem and get customer service involved individually, but has this happened to others?
