This course starts on the shore of Folsom Lake near the Rattlesnake Boat Ramp. The trail follows the shoreline upstream to the Auburn Dam Site and then climbs uphill to Overlook Park. 30 k runners will refill their bottles and turn around here while the 50 k runners will continue along the Tevis Cup and Western States trails to the No Hands Bridge Aid Station. A quick trip up the Training Hill brings you to Cool side of the canyon. Some brief rolling terrain and then it's back downhill to No Hands Bridge and then back the way you came to the start/finish area.
