Woodside Crossover

Woodside Crossover is a trail running event on April 17, 2027, held at Huddart County Park and Purisima Creek Redwoods Open Space Preserve on the San Francisco Peninsula. The event uses forested single-track and fire roads through second- and third-generation redwoods, mixed evergreen forest, and chaparral ridgelines. Wildlife on the route may include black-tailed deer, coyotes, bobcats, and gray foxes.

Distances offered:

  • 10K : 6.5 miles, 1,400' elevation gain
  • Half Marathon : 13.0 miles, 2,950' elevation gain
  • 35K : 20.0 miles, 4,500' elevation gain
  • 50K : 30.8 miles, 5,750' elevation gain

Most of the course runs on moderately technical dirt trails and non-technical fire roads. Hiking poles are permitted. Courses are marked with colored surveyor ribbon, laminated signs at complex turns, and occasional flour arrows; blue ribbons indicate wrong-way trails. Aid stations provide energy gels and chews, snacks, salty foods, Coke, water, Skratch Labs hydration, and basic first aid supplies. The event is cupless; runners must carry a bottle or reusable cup. Disposable timing chips are attached to the back of each bib.

Other details: capacity is 400 runners across all distances; drop bag service is not available; parking in the park is $6.00 cash only; dogs are not permitted in the park or on the trails. Awards include overall and age-group prizes, finishers' medals for all distances, and a pint glass for all 50K finishers. Visit the organization's website for the most recent information.
