The event is a fundraiser for the Bay Area Ridge Trail. One hundred percent of entry fees are donated to the Ridge Trail Organisation. The event is organised by Friends of Ridge Trail in partnership with Ridge Trail.

Courses

The 10K starts at Skyline Open Space Preserve and follows trails toward Monte Bello OSP, climbs to Black Mountain Summit, then returns on Indian Springs Trail to Skyline OSP. Hikers are welcome.

The 21K (half marathon) runs through Skyline Ridge and Russian Ridge Open Space Preserves, with a mix of narrow hiking trails and wider ranch roads. The route includes open grasslands, high knolls, and intermittent shade on south- and west-facing slopes. Aid stations are noted at Russian Ridge (mi 5), Skyline OSP (mi 10), and Monte Bello (mi 12). Hikers are welcome.

The 50K is run only. It traverses moist evergreen forest, oak-madrone woodlands, and high grasslands across multiple open-space preserves and a county park. The route includes Skyline Ridge, Russian Ridge, Black Mountain, and sections toward Stevens Canyon and Longs Ridge. Views include the Santa Cruz Mountains and, on clear days, the Pacific Ocean.

Logistics

Aid stations will provide water, Tailwind, fresh fruit, PBJ, soda, and gels. A water faucet is available near Black Mountain campsite on the 50K route. The finish area includes hot food for finishers. GPX files are available for the half marathon and 50K courses.

Courses will be marked with pink ribbons and red flags; wrong routes are marked with blue ribbons. Around turns, red/black striped ribbons will be used.
