I'm gonna run a race, I'm not getting first place!

I'm probably nuts but this Saturday I'm going to be running the 5K race for the Gasparilla Distance Classic held here in Tampa. I was roped into doing it by my wife and her maid of honor. I'm probably going to be able to run the first 100 feet then probably will need assistance from an oxygen tank since I've never in my life run a race. I think its been close to a decade since I've had to run for any type of reason at all. I'll blog about it later if I'm not in the emergency room dying from a heart attack.
