Course and logistics
Courses run on rolling single track within McDowell Mountain Regional Park and the McDowell Sonoran Preserve. Trails include the competitive track and newer trails such as Coach Whip and Dixie Mine. The 50 Mile course includes three out-and-back climbs (East End, Windgate, Thompson Peak) and a large loop before returning through the start/finish area. The 50K is a single loop that uses Escondido Trail, parts of Pemberton loop, and preserve trails.
Aid stations are well stocked and located roughly every 3 to 10.5 miles. Drop bags are permitted for specific distances and stations (Dixie Mine and headquarters for 50 Mile; Dixie Mine for 50K; start/finish area for shorter distances). Crews may access the start/finish area only. Pacers are allowed only for 50 Mile runners on the final loop within the competitive track. The park charges a $7 entry fee per vehicle. Courses are marked with orange ribbons, reflective medallions, laminated signs, and wrong-way flagging. Medical staff are based at the start/finish headquarters.
