Course intelligence

Know the course before you race it.

Terrain

Sand Hollow Reservoir swim. Brutal hilly bike through Red Rock Canyon with 4,500 ft of climbing — the hardest 70.3 bike in North America. Technical run through St. George.

Conditions

May in southern Utah: 65–85°F, low humidity, high UV. Elevation ~2,800 ft at race start. Wind through the canyon corridors is notoriously unpredictable.

Aid Stations

Four bike aid stations; run aid every mile. Limited aid on the bike means self-sufficiency is critical.

Key Challenge

The hardest 70.3 bike course means athletes arriving at T2 already severely depleted. Running well after this bike requires exceptional nutrition discipline.
