Course intelligence

Know the course before you race it.

Terrain

Six-loop desert course through McDowell Mountain Regional Park. Flat to rolling singletrack with cactus and desert scrub. Total climbing ~6,600 ft.

Conditions

Halloween weekend in Scottsdale: 50–85°F. Starts warm, cools significantly at night, warms again the second day. Desert air is very dry.

Aid Stations

Massive Javelina Jeadquarters aid station at the loop start/finish — plus one mid-loop station. Crews have full access at Jeadquarters every 15 miles.

Key Challenge

Six loops of the same course creates severe mental fatigue and GI monotony. Athletes stop eating because every meal feels like the same meal they've had five times. Food variety becomes a survival skill.
