Course Information:


The 2 mile run course is the same for both legs of the race. The course will run on granite paths, single track trails, and a small section on pavement with an aid station at the start of the run and the half way point.


The bike course is on multi-use trails within the Granite Bay State Park on Folsom Lake. The course features a fun, challenging combination of twisting single-track, wide double track, rolling cross-country with lots of turn that flow beneath the oak and pine forest. The course is perfect for first-timers and exciting fun for all levels. Please be respectful of other trail users including hikers and equestrian riders in this state park. All events are rain or shine, the course is great to ride in all weather.
