The event uses Proxima C Endurance Fuel as its electrolyte and carbohydrate beverage.

Camping is allowed during the race in a designated area at no charge. City rules restrict stake depth to six inches and require pop up shelters to be weighted with at least forty pounds per leg. About twenty RV permits are available for a fee that will be donated to the City of Loveland.

Crew assistance is allowed only in designated areas. Pacers are not permitted. Course cutting, littering, entering the course improperly, or bringing dogs on course can result in disqualification.

Buckles are awarded for finishes at 50 kilometer and greater; a 50 kilometer minimum is required to receive a finishing buckle. Deferral and withdrawal credits are issued on a sliding scale up to 45 days before the event. Visit the organization's website for the most recent information.
