About the race

Peacock Gap Trail Run takes place at China Camp State Park in San Rafael, CA, and offers three trail distances with substantial elevation gain. Courses run on moderately technical dirt single-track and non-technical fire roads, with a notable climb beginning about 1.5 miles into the route and long sections that open onto the San Pablo Bay side of the park.

Distances include:

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

Courses are marked with colored surveyor ribbon placed approximately every 200 meters, heavier markings at turns, laminated signs, and flour arrows where allowed. Blue ribbons mark wrong way trails. Hiking poles are permitted. Aid stations provide a variety of foods and drinks such as energy gels, stroop waffles, trail mix, pretzels, potato chips, PB&J sandwiches, boiled potatoes, Coke, ginger ale, water, Skratch hydration mix, salt tablets, and seasonal fruit; first aid supplies are available but no anti-inflammatory medicine. The event is cupless so runners must carry their own reusable cup or bottle; reusable cups and 500 ml soft flasks are offered for sale at the event.

Timing is chip based using MyLaps and Race Director with disposable bib chips. Parking is free along N. San Pedro Road at the Miwok Meadows entrance with a short walk to the start area. Capacity is 275 runners across all distances. Awards include custom trophies for the top three overall and medals for all finishers and age groups.
