Seriously, lighten up, Dude. You won something. If it costs you $10 for not sticking around to claim your prize, so be it. Your money prize also has a plaque with it. I know because I was there for the awards - to get mine. Crazy me, stuck around for the marathon awards that began close to @ 11:30am - four and a half hours after the marathon start. Please, let me praise you for being so super fast! Three hours would be a REALLY long time to wait if you won your prize money by finishing your marathon in under two hours. Wow, you really rock. With your elite status, it's a wonder they didn't just hand you your check and crummy plaque at 7am at the starting line and save everyone the trouble.
Now if by chance you were exaggerating slightly about the awards ceremony delay - please read on.
Make the RD an offer - send him a SASE for your check and tell him to throw out the crummy plaque that means nothing to you. Collect your winnings and pride yourself on knowing you got the better of the deal, hell you will have saved yourself $10 less $.82 in postage and the cost of two envelopes, of course. BUT YOU WILL HAVE WON AGAIN! Because that's what really matters to you. Winning, right? You have to win this one over the RD - just like you won the prize money from those CHEAP BASTARDS who want to give you money for running...hmmmmmm. Imagine that, prize money to arrogant and apparently clueless runners("I had no way of knowing I had won". Hello Crock, looks like you are full of something - just say you blew off the awards and figured they'd send you the check and you got your running shorts a little twisted when they wanted to nip you the $10.
Man, you are right though (there you go, winning again, damn you are good!). They are cheap and you are awesome. Perhaps those of us who ran and stuck around to pick up our awards could start up a collection to cover the cost of getting your award to you. Maybe we could just get everyone together at a time that would be convenient for you and re-enact the awards ceremony, well just your check presentation. Hell, let's just get a limo, balloons, a GIANT check and Ed McMahon to deliver it personally to your door...wait, that may be going a bit too far with Mr. McMahon's current condition and all.
Besides, you won money at a race, you didn't cure cancer.
