Listed edition: Mar 29, 2027 – Apr 4, 2027
Format: 200+ Mile
Distance: 300.5 mi
Local start time: 12:00 PM Monday
Duration / cutoff: 150 hours
Crew and pacers: Crew are optional, and the organizer says many runners finish without crew or pacers. Crews may meet runners at the start, the finish and seven aid stations: Gabe Zimmerman (mile 81), Rillito (126.3), Catalina (144.5), Mount Lemmon (171.2), Freeman (224.4), Grand Enchantment (256.9) and Gila River (273.2). Contact anywhere else is a disqualification. Each runner gets one crew parking pass for a vehicle no longer than 20 ft or wider than 8.5 ft, with no RVs, trailers or crew camping at aid stations, and crews should arrive no more than 30 minutes before their runner and leave when the runner does. Pacing is allowed from Rillito to the finish, one pacer at a time, with pickups only at crew stations. Pacers wear a pacer bib, carry the full mandatory kit including their own bivy, and may not carry the runner’s gear, food or water.
Drop bags: Optional drop bags go to the start, the finish and 12 aid stations: Apache Springs (mile 36.8), Oak Tree (52.5), Gabe Zimmerman (81), Pistol Hill (91.3), Rillito (126.3), Catalina (144.5), Charlou Gap (151.4), Mount Lemmon (171.2), Tiger Mine (194.7), Freeman (224.4), Grand Enchantment (256.9) and Gila River (273.2). Bags can be no larger than 16 × 24 × 10 inches, no coolers, and must be labeled with your full name, bib number and aid station. Hand them in at check-in in Superior; they must be in place by 5 PM the day before the start. Bags come back to the finish only after each station closes, they are not mailed, and unclaimed bags are donated or thrown away.
