The geography of the Acton Recreation Area consists of high-plains terrain characterized by single-track trails through sagebrush and technical sandstone features. Mountain bikers compete on an approximately 8-mile course known for fast descents and steady climbs; notably, E-bikes are permitted and have their own dedicated award category. Runners utilize a separate 4-mile loop featuring gentle elevation changes. In early May, the Broadview region typically experiences cool to mild spring weather, with average daytime highs of 16°C (61°F) and nighttime lows dropping to 3°C (37°F). Overnight runners are required to use headlamps and reflective gear for the 24-hour segment.
Logistically, the event promotes a "primitive" experience. The race site on Heag Road has no running water or electricity, requiring participants to bring all necessary supplies for camping and self-sufficiency. However, the organizers provide a central aid station with basic nutrition, water, and hot meals, including soup and coffee for those running through the night. The event concludes on Saturday evening with a communal free meal for all participants. Profits and participation help support the maintenance of the local trail systems outside of Billings.
