Peter Williams is a 6-foot-tall, 46-year-old man riding a little girl's bike! His unique activity is for a good cause: to raise money in tribute to his daughter Ellie, who died of a rare brain tumor three years ago. Ellie loved sports, especially biking. His goal is to trek 30 miles a day on a bike designed for a 7-year-old. He's already doubled his goal of raising 10,000 pounds, or over $13,000.
