A few years ago I learned about Masters Track. It's for past your prime people that still love to compete in track. At 45 I still love to sprint. I'll be racing in a college meet in Columbus March 4th against college teams. I've run in 2 of these kind of meets in the past several weeks. I ran 8.2 in the 60 meters and 7.7 in the 55 meters. I actually beat a few of the college guys. It's been fun competing again at my age.  If you want to compete, check out directathletics.com. I think the deadline for signing up is tuesday.
