Course and support
Courses run mostly on technical dirt trails and non-technical fire roads; hiking or trekking poles are permitted. Elevation gains listed for each distance are provided on official course files and profiles. Courses are marked with colored surveyor ribbon approximately every 200 meters; blue ribbons indicate the wrong way. Aid stations provide a range of food and drink items such as energy gels, Stroopwafels, trail mix, PB&J, soda, water, Skratch Labs hydration mix, and general first-aid supplies (no anti-inflammatory medicine). This is a cupless event; runners must carry their own water bottle or reusable cup. All finishers receive a custom medal and the top three overall finishers per distance receive trophies; age-group awards are given by chip time. Race shirts are tri-blend performance tees; a registration date is provided to guarantee shirt size. Visit the organization's website for the most recent information.
