The event provides a semi-stocked aid station offering liquid nutrition, energy gels, protein bars, and water. While these supplies are available, runners are encouraged to be self-sufficient. For longer distances like the 101 Miler, 100 Kilometer, and 24 Hour Run, pacers are permitted at any time.

The course is staged in the Spokane area, utilizing locations such as the Reardan Cross Country track in Seven Mile and Riverside State Park. Participants in the 101 Miler and 100 Kilometer receive a buckle upon completion, while other distances earn specific patches. All registered participants receive a training tee. There is space available for tents in a designated section of the parking lot for crew access. Visit the organization's website for the most recent information.
