I'm the race director so I can tell you first hand that any money you pay to join the race will go directly to helping house homeless veterans. So stop waving the flag around and put your hand in your pocket so you can take out your wallet.
Hard core athletes will be running for 24 hours but will stop on the top of every hour to do a challenge. 60 pushups, 120 air squats, 75 burpees, that kind of thing. Or you can just run 24 hours. Or 12. Or just five minutes. It is up to you.
I'm going to be moving for the full 24 hours and doing all 24 challenges. Anyone here signs up and beats me then I'll give them my axes.
