Pre-Ride/Run

If you are planning pre-ride/run the course, it is highly recommended you print out the course map, course description listed above, and this map of all of the trails on the Frisco Peninsula. The course can be tricky to find on your own as some of the trails are unmarked or have confusing intersections. Please know that the course will be marked extremely well for the race.

Also, if you do pre-ride/run the course, we recommend you park at either the Frisco Adventure Park or in the Two Below Zero parking lot that is located just after you turn from Recreation Way onto the Campground Road. This is a mulch lot and is labeled “Two Below Zero Parking”. If you choose to park at the actual transition area, you will have to pay a $8 USFS fee per vehicle.
