Named obstacles listed for the event include Arctic Enema, a roughly 34 degree ice pit; Everest, a greased 13-foot quarterpipe; and Kiss of Mud, which places a barbed wire element approximately 14 inches above the ground.

Entry options include individual competitor, a four-person team relay, pit crew / spectator passes, and a post-event brunch. Listed starting prices are $406.13 for individual and team relay entries, $29.04 for pit crew passes, and $45.36 for the brunch option.

Athletes receive an event bib and a finisher headband. Medals are awarded to athletes who meet the event’s top-tier criteria, and qualified Contenders are eligible for additional prizes and a finisher shirt. The venue’s pit area offers reserved campsites, food trucks, music, event announcers, and a full race center. An Adaptive Athlete Programme pairs athletes with course guides to assist on course sections. Visit the organization's website for the most recent information.
