Course, aid stations and logistics
Courses run mostly on technical dirt trails and non-technical fire roads, and the hills can be steep. Hiking or trekking poles are permitted. Courses are marked with colored surveyor ribbon placed about every 200 meters; blue ribbons indicate wrong-way trails. Detailed maps, turn-by-turn directions, aid station distances and elevation profiles are provided in printable files.
Inside Trail Racing aid stations supply a variety of food and drink options, including energy gels, stroopwafels, trail mix, salty snacks, PB&J sandwiches, Coke, water, and Skratch Labs hydration mix. This is a cupless event; runners must carry their own bottle or reusable cup. Drop bag services are not available. There is a 6.5 hour time limit for the 35K race. Parking is available at the Chabot Space and Science Center. Dogs are allowed on leash; runners who bring dogs must start at the back of the pack.
