The XTERRA Boney Mountain Trail Run takes place in Point Mugu State Park. We start on the northern edge of the park in Rancho Sierra Vista/Satwiwa National Park in Newbury Park (just west of Thousand Oaks). This event is the Grand Daddy of the series and is not for the faint of heart. But if you dare to enter, you’ll experience some of the most scenic backcountry in the Santa Monica Mountains. The 6K is a great intro event with paved roads and singletrack along Upper Sycamore Canyon while the 21K is a fun challenge who love to go long.
