Course and race logistics
The route runs on trails around Montara Mountain and is marked with ribbon about every 200 yards. Color-coded flagging is used for each distance and polka-dot flagging marks turns; blue ribbons indicate the wrong way. Headphones are allowed on dirt road sections only. No dogs are allowed on the course.
Elevation gains and surface types vary by distance: the 10K has about 1,200 ft gain; the half marathon about 2,900 ft; the 20 mi about 4,640 ft; the marathon about 5,840 ft; the 50K about 6,700 ft. Most courses are largely single-track, with smaller portions of dirt road and asphalt; exact percentages vary by distance.
Aid stations are fully stocked every 6 to 7 miles with fruit, salty snacks, candy, water, and Skratch electrolyte drink. The event is cupless; runners should bring a personal fluid container. All events have a 9-hour time limit. Race-day check-in and packet pickup are at the Walnut Grove picnic area; drop bags are allowed for 20 mi, marathon, and 50K.
