So today I had my first run using a heart rate monitor. It was kind of weird to use it. I'm going to have to look up training with it. I set a zone and stayed w/in it for most of the run, but found that it actually slowed my pace. I'll play with it to figure out how to use it best for my workouts. I thought it would be uncomfortable, but it wasn't. It was actually very comfortable to use, but man was it sweaty when I finished my run.
