It was cold one today.
Also had a bit of a drama. 2 miles in and a little check of my mileage on the Garmin…
Flat battery. I had checked before I left, it was about 40% so not sure what is going on with the watch.
So I tracked the second half of the run using Strava on the phone. It was 4.38 miles overall.
Totals:
Runs = 4
Mileage = 15.85

The Garmin might not have liked the cold weather. Well done for getting out there!
