Uh...I don't know? The only thing I can recall winning that was sorta like a race was some odd experiment for biology class where everyone took turns to run up two floors worth of stairs (ground floor to second floor of K-Block for you EL because you'll know where I'm referring to) and our times were recorded and I got the best one. Not sure if that's a race or not though.
Have you ever entered a legit competition? (By legit I mean not counting stuff like a forum caption contest or something casual like that.)
