Course and logistics

The course passes through redwoods and ferns on single-track trails, dirt roads, and some asphalt. Distances were measured with a Rolatape surveyor's wheel. Elevation gain by distance: 8K 710', Half Marathon 2,190', 35K 2,990', Marathon 3,790', 50K 4,530'. Single-track makes up the majority of longer courses.

The route is marked with colored ribbon and polka-dot flagging to indicate turns; blue ribbons mark wrong directions. Headphones are allowed only on dirt road sections and are not allowed on single-track, when crossing paved roads, at aid stations, or at the finish. Aid stations are fully stocked every 5 to 9 miles with fruit, salty snacks, candy, water, and Skratch electrolyte drink. Runners are advised to carry at least 20 oz of water between aid stations. The event is cupless; participants should bring their own fluid container.
