That darn metric system

Earlier this week I had a conversation with my nephew, a member of the local High School track team, about the actual diameter of the HS track. I discovered that I had made a bad assumption about the distances I was running as I had assumed the measurements were in quarter mile increments. He told me the track is measured at 1600 meters around. That explained why my Nike+ Sportband was off when I thought I was running my measured distances. What's puzzling is that when I measure the track using the extremely accurate Google Earth ruler tool the distance around is actually .26 miles or about 4% longer than a quarter mile. It should actually be shorter than a quarter mile, not longer. Either way I now know the actual distance so I can calibrate accordingly but I'm obviously missing something.

Today I did 25 minutes of upper body work to rest my legs but later in the day I went over to the track with my wife and kids because the kids wanted to run. Instead of doing laps I did sprints to work on my fast twitch muscles and anaerobic conditioning. I'm not used to running that fast and started to develop some tightness in my leg (different from my previous muscle pull). I stopped right away and iced it when I got home. I'm not taking any chances. Tomorrow I plan to run 3+ miles as my training for the April race continues.
