Dave, you might consider a foot race as well. Not sure if very many could make it all the way around the track, though.

Or.....a sack race with Marv and one of the 50/50 ladies in one sack (uh, that's one leg each in the sack!:2 with you and Chuck in the other.

Or....a bicycle race, one with kids and one without. (Not to mention a tricycle race. I'm thinkin' that Aero would look good on a trike.)

Or...a cage match with John Hoover vs. The Sword Man.
