Course Details
The course is marked with color-coded ribbons approximately every 200 yards. Polka-dot flagging indicates turns. The terrain is a mix of single-track trail and dirt roads, with no asphalt sections. Detailed elevation gain and surface breakdown is provided for each distance. For example, the 5-mile course has 960 feet of elevation gain and is 66% single track.
Aid stations are located every 5 to 6.5 miles, offering fresh fruit, salty snacks, candy, water, and Skratch electrolyte drink. The event is cupless, so participants need to bring their own fluid container. Parking at the venue is free.
