Interval Work!
This morning I did four 600m intervals on the track, which was definitely a welcome break from all the long, steady running I've been doing. I'm not sure how accurate my Forerunner was in measuring the distance, because I think it's a 400m track and my little buddy wasn't giving me exactly 400m every time I went around, but it's not so much about the specific distance than it is about the general time and speed. After the 4 x 600m, I did 1 x 200m and then headed into the weight room to get my lifting in.

Oh, how exciting. I have just rediscovered intervals, too (courtesy of my training plan, which tells me to do them). They are great. But I thought the purpose of the track was to have a precisely measured distance -- why are you using your GPS to find your distance on a track, of all things?

I used my Forerunner on the track because I was interested to see how accurate it actually is. Plus, I couldn't do my intervals on the pavement, and the Forerunner has this really handy feature that helps with timing intervals and such...

GPS is accurate to within one meter of your actual position, which is good enough for almost every purpose, including the military. (It used to be within 10 meters because they purposefully put noise in it so that other militaries couldn't use it.) But if you're trying to measure distance in a very small area, I suppose it could give you issues. I'd try it on a measured distance that was more straight if I wanted to gauge its accuracy.
