Carbohydrates often get a bad rap, but not when it comes to athletes. Carbs are the fuel in the runner's tank and that fuel can come in many forms -- one of them is bananas. Both triathlete Haskins and marathoner Wardian list bananas as a staple of their post-run diets [sources: Haskins; Wardian]. But neither of them eat bananas alone.
Haskins puts hers in a smoothie with almond milk, peanut butter, honey, ice and cocoa powder. Wardian eats his with a glass of skim milk. Supplementing that banana with a source of protein -- as Haskins and Wardian do -- will top you off right.
