What are the qualification requirements for participation?

This event is not open to all runners. Participants must be members of the Sky Pilots Endurance Navigators and demonstrate sufficient mountain experience, specifically:

• →Navigating rugged off-trail terrain (scree, boulder fields, snowfields, etc.)
• →Independent mountain navigation under difficult conditions
• →Ability to perform weather assessment and appropriate gear selection in alpine environments

Note: Completing 100-mile races like Hardrock or Barkley is not considered sufficient justification; the emphasis is on specific off-trail navigation skills.

What are the time limits and support levels?

• →Cutoff time: 19 hours
• →Support: Minimal, consisting of only a couple of basic checkpoints providing calories and fluids.
• →Remote Nature: Much of the course is remote, and rescue operations could take hours or days.

What weather and gear considerations should I be aware of?

Due to the high altitude and terrain, some years require ice axes and traction devices. Participants must be prepared for alpine environments. For river crossings, please monitor these gauges:

• →Mineral Creek (crossable when under 2 ft): Usgs ↗
• →Animas River (good when under 3 ft): Usgs ↗
