Course Description and Map

There will be One Mass Start for all competitors. The swim will be marked with large orange buoys placed in a counter-clockwise triangle. The .5-mile swim course is in Folsom Lake. Water temperature should be approximately 50 degrees. Wetsuits are recommended. Upon exiting the beach you will run through a timing chute where your numbers will be recorded for your swim split times. If your number is not recorded, you will not receive a swim split in the final timing. You will continue up the beach to the transition area where your bike is racked. The course will be patrolled by the TBF Water Safety Team and assistance is available to any swimmers experiencing distress.

The 16-mile mountain bike course is a 2-lap course located entirely within the park on mostly single-track trails around Folsom Lake. The course has a few climbs and descents, nothing technical or with any rocks or major obstacles. All levels of riders will be able to enjoy the course.

The 4 mile run course leaves transition and runs on single- track trails along the lakeshore and back towards the transition area and finish line. There is a hill at the halfway point. The out and back course has 3 aid stations that will be stocked with water, Gatorade, and GU. The finish is back at the start area at the Main Beach.
