Tantalus Triple Trek

Tantalus Triple Trek is a trail ultra put on by HURT Hawaii in Honolulu, Hawaii, on September 12, 2026, starting at 5:30 AM. The event offers a single 30-mile format (48.3 km) on the trails of Tantalus, above the city, and the name points to a course that takes on the mountain three times.

Thirty miles on Hawaiian trails is a demanding day, with heat, humidity, mud and steep climbing all likely to feature. It suits runners with 50K experience or strong trail runners looking for a first ultra in a tropical setting. Because the terrain slows everyone down, train by time rather than distance, include long hikes on steep ground, and practice descending on slick footing. A 16-week build with back-to-back long runs and consistent hydration practice will set you up.
