Heart Rate Monitor for 5K

Today I participated in a 5K “run” which equates to about 3.1 miles. I’m not really sure how far I went because the trails weren’t marked with which direction to go so I had to turn around and go back. All in all though, I was walking/jogging for 1 hr and 10 min. I had my heart rate monitor on to see how many calories I burn when I run and what my heart rate is, of course. Anyways, it was about 540 calories. Pretty nice considering if I was just to sit in a chair and do nothing that I’d only burn about 120 in an hour. It’s not that I didn’t know that exercising burned calories, but it’s good for me to see the numbers.
