I would be interested in doing one. Especially if it was in Indy, Cincinnati, or Louisville! (I would be open to other places too, those are just easiest for me.)
I'd totally do a relay as long as ya'll don't mind how slow I am. I'd even travel for it.
I could be convinced to do Detroit but I'm already planning to do bike support for the race for my friends that are running (ride my bike out to the distant points of the marathon to provide gu/gatorade/cheering as needed).
