What I didn't realize at first is that there will be at least a 20 degree difference. My run today was in 30 degree weather, tomorrow is supposed to be 50 degrees (perhaps I'll steal a run in tomorrow too...we'll see how things are going).
Although the weather was on the cold side, I was really looking forward to this run. It was the first with the Garmin Forerunner 305!
I did my neighborhood lake route - 3.24 miles when I mapped it out previously...Garmin says 3.18 miles. I guess I'll be running into this pretty often.
The thing I liked best about the Garmin was that it gives your splits as you hit each mile. I happened to look at the watch at all three splits - 11:07, 11:00 and 10:58. Pretty consistent. Average HR was 155 bpm. Not a bad run for a first time back.
I'm definitely looking forward to more runs with my Garmin!
