Also the only race I've ever won, although I won it both years it's been held. It was a 5k in my college town, and I actually was involved in putting it together for a charitable organization. There were about 200 finishers both years, 90% of whom were walkers/joggers. I make no claims to be fast (although my PR is well under the winning times), but I won the 2006 race with an 18:18 and the 2007 race with an 18:08.
I've finished 2nd and 3rd in a bunch of races, once to a guy I usually beat. I finished 2nd to him in a 5k I impulsively ran the morning after sleeping with my then boss, and it turned out that 1st prize was free entry to the Baltimore Marathon and a gift certificate for a pair of running shoes at a local running shop. Considering I usually beat the guy and finished 50 seconds off my PR, I was pretty pissed.
