Profiles

The full marathon is an out-and-back that begins on Black Star Canyon Road. The course follows the creek into the canyon on a relatively flat truck trail (with a slight gain) for approximately 2.5 miles. At the falls turnoff, the course switchbacks up into the Mariposa Reserve, where it continues up toward the top for ocean and Inland Empire views. The Runners take Black Star Canyon Road until it ends at Skyline Drive and N. Main Divide (known as Leonard Road at this location). From there, they run down Skyline Drive into Corona, where they return to the Finish the same way. The elevation gain for the marathon is about 4,244’.

The half marathon begins in the same location. Runners also follow the creek into the Black Star Canyon, and then switchback up into the Mariposa Reserve. The course continues up the truck trail past the historic Indian village, adding a few more switchbacks with spectacular canyon views.  About a mile shy from  the top, the course tuns around and returns to the Finish. Elevation gain for the half marathon is about 1,773'.

The 10k begins the same as the full and half marathons. Though the 10k course is mostly “flat” (with a slight gain), runners will climb some "quick”, steep switchbacks up Black Star Canyon Road for a scenic view looking back into the canyon. From there, the course returns to the Finish. Elevation gain for the 10k is about 706'.
