      Cyclist: 'We ride for Cancer'

      Palo Duro Canyon is usually known for its hiking trails, but this weekend it's known for nothing but cyclists controlling the roads for 24 Hours in the Canyon.

      Its tag line reads "Cancer doesn't sleepâ?|Why should we?" and that's because within 24 hours a majority of the cyclists get no sleep at all.

      Hundreds of cyclists have been in town since last night participating in the night climb challenge. Cyclists from Colorado, New Mexico, Oklahoma and all parts of Texas are taking part in the fight against cancer. Saturday kicked off the competitive 4-person team race. Each team member bikes for about 6 miles at a time, then hands off a chip to another person. Teams bike these laps for a straight 24 hours, or as long as they can.

      There is also a non-competitive race on the other side of the canyon, where families and their kids take advantage of the empty canyon roads.
