My Garmin 910XT is dead (again). Yesterday, it gave me some issues but after reading the Garmin support blog and cleaning the charger connection points with some Formula 409, it started working. Today, I had no such luck. So I called Garmin support and the good folks at Garmin are going to overnight me a new unit at no charge. I love their customer service.
I ran today for 45 minutes with no Garmin and no heart-belt. It was a slow, easy run. My calf muscles are still sore and my left bit toenail still hurts (it is about to fall off). It was good to run with no equipment! It felt free although not easy. It was warm and sunny; not ideal running conditions!
