Course and logistics

Courses run through Huddart Park, King's Mountain and Bear Gulch with redwoods, ferns, and mixed trail surfaces. Courses are marked with colored ribbon about every 200 yards and polka-dot flagging to indicate turns; blue ribbons mark wrong directions. Headphones are allowed on dirt road sections only and not allowed on single-track trail, when crossing paved roads, at aid stations, or at the finish line.

Elevation gain and surface by distance: the 8K has about 710' gain; the half marathon 2,190'; the 35K 2,990'; the marathon 3,790'; and the 50K 4,530'. Surface mixes include single track, dirt road, and small asphalt sections.

Aid stations are fully stocked every 5 - 9 miles with fresh fruit, salty snacks, candy, water, and Skratch electrolyte drink. Runners are recommended to carry at least 20 oz of water between aid stations. The event is cupless; participants should bring their own fluid container. T-shirts go to pre-registered runners, all finishers receive a custom medal, and 50K finishers also receive a custom coaster. Parking is $6 per vehicle. No dogs are allowed in the park.
