Crossroads at the Chicago Marathon: Heart Monitor

I just got this inexpensive Omron heart monitor and used it for the first time this morning. It works great.

I actually found that I had to bump my speed up just a bit from what I had been doing. But maybe that was just because I don't usually run first thing in the morning. My breathing felt about the same.

My heart rate range for an aerobic workout is 130-145bpm. That put me at about 6.5mph at the beginning. I had to notch it down a bit by the end to keep it in that range and ended up with a 10:19 minute mile average including warm-up and cool-down for 4 miles.
