Elite ultra-marathoner Michael Wardian has no special powers, although he holds the Guinness World Record for fastest marathon run as a superhero (Spiderman). He has to refuel like the rest of us. When he's extremely hungry, he reaches for oatmeal [source: Wardian].
Oatmeal is a great post-run food because it contains carbohydrates, protein and fiber. Fiber makes you feel full so you don't risk over-indulging. Sound a little bland? Top it with a fruit of your choice to make it both healthy and tasty. An added benefit -- the fiber in oatmeal has been shown to reduce bad cholesterol [source: Mayo Clinic].
