Sounds like a great idea Marty. I'm 5'8" also, and probably around 208-210 right now. I ran a 1/2 marathon last September, and quit running after that.

So, I pledge if I get down to 165 (I've been there before!) by January of 2011, I'll donate $200.

As a bonus, if I throw in another $100 if I do a full marathon (at some point to be determined, I have no idea when/where marathons are around here near the end of the year)

I should point out I do plan on participating in one of the Ragnar Relay's, so that is a short-term goal.
