Peacock Gap Trail Run

The Peacock Gap Trail Run is a trail race held at China Camp State Park in San Rafael, California. The event offers multiple loop distances:

  • 30K (19.5 miles, 2,735′ elevation gain)
  • Half Marathon (13.1 miles, 1,800′ elevation gain)
  • 10K (6.3 miles, 1,140′ elevation gain)

Courses run mostly on moderately technical dirt single-track and on non-technical fire roads. Runners encounter a sustained climb beginning about 1.5 miles into the routes, followed by descents toward the San Pablo Bay side of the park. Hiking or trekking poles are permitted.

Courses are marked with colored surveyor ribbon placed about every 200 meters, with additional laminated signs and flour arrows at complicated intersections. Blue ribbons indicate wrong-way trails and should not be followed. Aid stations provide a selection of energy gels, chews, stroop-waffles, salty snacks, sandwiches, fruit, soda, electrolyte mix, and basic first aid supplies. Runners are encouraged to carry at least one 20 oz bottle because distances between aid stations vary.

The event is cupless; runners must carry a reusable cup or bottle. Reusable cups and 500 ml soft flasks are sold at the event. Timing is chip based with disposable chips attached to bibs. Capacity for the race is 275 runners and parking near Miwok Meadows is free with a short walk to the start area.

Awards include custom trophies for top three overall finishers by gender, finisher medals for all, a Dead Last Finisher award, and age-group medals awarded three deep including a non-binary category. Visit the organization's website for the most recent information.
