Runners will be supported with 12 aid stations along the course, about every 4 to 7 miles. Nonetheless, runners must have the capacity to carry at least 34 ounces (1 liter) of water and 200 calories of nutrition. (Click here for the list of required gear.)
Personal crew and drop bags will be allowed at the following aid stations. Each of these crew-accessible aid stations is family-friendly and has easy access via paved roads. We’d prefer that dogs are kept safe at home, but if you must bring them, please keep them on-leash. Dogs must not be left in vehicles unattended. Dogs are not allowed on-course at any time.
- A4 / Johnson Canyon / Mile 24.5
- A9 / Van Norden / Mile 50.0
- F / Finish – Sugar Bowl / Mile 62.3
Each aid station will offer Skratch Labs and GU Energy Gels, in addition to a selection of solid food products.
