Participants can compete individually, in pairs, or as teams, and the organizer states prior fitness race experience is not required. Staff are stationed to guide participants through the exercises, and the timing chip tracks running, station completion, and transitions. Entry includes a STYREKX Patch, and finishers receive nutrition, a personalized results breakdown, and a certificate; facilities like changing rooms, a cloakroom, and a hydration station are also provided.
