Staggered starts are used and participants are expected to travel independently.
Control points are mandatory but may be visited in any order. Elective controls carry point values; a full finish requires elective controls totaling six points in addition to non-elective controls. Ptarmigan Overlook will be an unstaffed control point in 2025 and must be visited twice. Teams may have up to three members and must carry a tracker with messaging capability. Crews are limited to designated checkpoints, legal vehicle access points, or specified hike-in crew routes. No pacers, no caches, and participants may not travel by vehicle while moving on course.
