Course details note a mix of single track, dirt road and asphalt surfaces, and elevation gain that increases with distance (from 710 feet for the 8K up to 4,530 feet for the 50K). The course is marked with ribbons about every 200 yards and color coded by distance; polka dot flagging marks required turns and blue ribbons indicate wrong ways.

Aid stations are fully stocked every 5 to 9 miles with fresh fruit, salty snacks, assorted candy, water, and Skratch electrolyte drink. Runners are advised to carry at least 20 ounces of water between aid stations. The event is cupless; participants are asked to bring their own fluid container. Some Hydrapak SpeedCups are available for purchase at check in.

Race day check in is at Huddart Park Werder Shelter; participants should arrive about 45 minutes before their event to receive bibs and shirts. Parking is $6 per vehicle; exact change is requested. Dogs are not allowed in the park. Headphones are permitted only on dirt road sections and are not allowed on single track, at aid stations, on paved crossings, or at the finish. The organizers note common trail hazards such as poison oak and occasional bees or yellow jackets. Visit the organization's website for the most recent information.
