A Brief Description

All routes start Loop 1 by heading south out of Creston on O'Donovan Road. All riders will turn right onto Highway 58, left onto Huer Huero, left onto Parkhill and then onto Pozo Road. At the intersection of Highway 58 and Pozo Road riders turn right onto Highway 58 for a couple of warm-up climbs before turning onto Highway 229 and the 1.4 mile hill climb challenge (KOM). The loop ends with a four mile shaded descent to a three mile open flat run into Creston.

At this point the Half Century riders are done and can head to the BBQ. The Century and 75 Mile riders have a rest stop in Creston before heading out for their second loop.

75 Mile riders will climb La Panza before turning right onto Highway 58 and then right onto O'Donovan and a 1 mile sprint challenge on the way to the finish in Creston and the BBQ.

Century riders will climb Highway 41 to begin their second loop followed by two great downhill runs on the way to Shandon. After Shandon there are 7 miles of rough pavement out Shell Creek Road that we refer to as our cobblestone section. The remaining section of Shell Creek is smooth and ends with a spectacular display of flowers if mother nature is kind to us. Riders then turn right onto Highway 58 and then right onto O'Donovan and a 1 mile sprint challenge on the way to the finish in Creston and the BBQ.
