Yesterday, I went to the Natick Track and ran 4 by 200 meter intervals for two hours. I have not been on a track since High School when I was a Sprinter on the Andover Girls Track and Field Team. I ran an 8 minute sprinting pace for each of the intervals. This is a great pace since my race pace is around 11 minutes.  I plan on going to the track more often so I can lower my pace time for my races.
