Biker Paul Cheal was near the bottom of the road when we caught up with him. He had crashed.

"I came around the corner and hit a loose rock," he said. "I tried to recover but couldn't. I was going too fast."

Cheal is O.K. He's not bloodied, but he's bruised and little humbled.

"I was finally having fun on the bike ride and then I fell. Too relaxed maybe," he said. (Jean Friedman-Rudovsky/ABC News)
