First try with the Garmin

Unfortunately, it was inside, and I hit the wrong buttons a couple of times, so it really did not do a good job of recording time. But it was an ID-10-T error (remove the hyphens, it's a geek joke), so it's my fault, not the Garmin's.

I did learn at least one important thing though: according to several formulas, my maximum heart rate should be either 185 or 203. It's at least 203 in reality, since the Garmin recorded my HR at 203 during my final, high-incline sprint at the end of the run.
