On Friday, March 23, former Marine Rick Hermelin will head out on his elliptical bike from South Carolina -- and just keep going. Hermelin, 71, plans to ride cross the country, reaching San Diego in 100 days. Minus food, which he'll buy along the way, he'll carry everything he needs in a small backpack.
He's raising money for the Semper Fi Fund, which supports injured and ill troops. "You just get started to push off and then it's just keep moving," he says.
