Bovada currently has Phelps as the bigger underdog:
Phelps +400/great white shark -700
vs.
McGregor +350/Mayweather -500
Great Gold vs Great White Betting Odds
Mayweather vs McGregor Boxing Odds
i'm not so sure, since the conditions of the Phelps/shark race are unknown. is it a draw if the shark eats Phelps?
when chris johnson and devin hester raced a cheetah, johnson lost and hester won, so who knows:
Devin Hester raced a cheetah, and won (Video)
