Never done it, but I looked it up and it looks like a sweet race. I'd definitely do it if I were you and it was still possible (is there a cap on registrants?).
Have you already regsitered? It says the deadline was March 31st. If not it sounds like you'll have to wait til next year. If so then good luck!
Holy crap
Yeah I'd definitely be all over that if I were you.
Found this in their FAQ section, in case you hadn't registered:
"
I didn't apply for the race or didn't get in through the lottery. What do I do now?
You are not the first, nor will you be the last. The majority of slots are allocated through the application and lottery process, so your options are limited. You may participate in the auction on July 3rd or you can purchase raffle tickets at $5 each for the opportunity to win one reserved slot.
If neither of those options meet your needs, we encourage you to participate in the race as a volunteer and be sure to apply for next year's race on January 1."
