Five 20-mile loops through the Ko'olau Mountains above Honolulu make HURT one of the most demanding 100-milers in the world. Muddy, rooty, technical, and relentlessly steep, the tropical trails of Oahu punish runners with humidity, slick footing, and unforgiving terrain that yields a notoriously low finish rate.

Nature Center Start/Finish

Each of the five 20-mile loops begins and ends at the Hawaii Nature Center in Makiki Valley. Runners check in here every loop, giving crews a chance to assess their condition in the tropical heat and humidity.

Tantalus Drive Climb

The steep road and trail climb up Tantalus through dense tropical rainforest. Banyan trees, bamboo groves, and Norfolk pines create a canopy overhead while the trail turns treacherously slick in the rain.

KM 19

Wa'ahila Ridge

The exposed ridgeline section of Wa'ahila Ridge offers some of the most technical running on the course. Roots, rocks, and steep drop-offs demand full concentration, especially in darkness and rain.

Manoa Falls Trail

The descent through the Manoa Valley toward the falls area is one of the muddiest sections of the course. Ankle-deep mud, stream crossings, and slippery roots define this quintessential HURT experience.
