Crazy Mountain 100 Map

The Crazy Mountain 100 travels through some intensely rugged and extreme terrain. You must be willing and able to navigate changing weather conditions and care for yourself in case of an emergency. This course is only for athletes in excellent physical condition free from injury. All entrants should be familiar with basic first-aid, and know the symptoms and treatment for heat exhaustion, hypothermia, frostbite, and altitude sickness. Some course sections between aid stations are over 13 miles. The course is primarily single track, with some forest road, two track, and there will be times you won’t even see a distinguishable trail and will be following cairns and ridglines. Runners should be well equipped to care for themselves and effect self-rescue if necessary. Because of the rugged and remote nature of this race we have rules we feel add to the underlying safety of this event.
