Olympic speedskater Chris Witty poses with her racing skates and bike Thursday, July 13, 2000, in Park City, Utah. In her Olympic dreams, Witty usually hears the rhythmic click and scratch of blades gliding over a frozen rink. This summer in Sydney, she'll hear rubber bicycle tires humming across a wooden track. It's a sound that could vault her into an elite group of Olympians. (AP Photo/Douglas C. Pizac)
