Dr. John Caton, a cancer specialist at Eugene, Oregon's Willamette Valley Cancer Center, spends his free time pushing himself both mentally and physically to go the distance. As an ultra cycle racer, Dr. Caton competes in bike races over 200 miles in length. It takes a great deal of hard work and a rigorous practice schedule, but Dr. Caton enjoys the challenge the sport presents.
