Hawaii Spartan Trifecta Weekend

Hawaii Spartan Trifecta Weekend returns to Dillingham Ranch on Oʻahu’s North Shore in Waialua for Aug 15–16, 2026. The event features four main races: Sprint 5K (20 obstacles), Super 10K (25 obstacles), Beast 21K (30 obstacles), and Ultra 50K (60 obstacles), plus a Kids Race. Racers navigate high-elevation climbs, coastal views, and gritty terrain across open fields, single-track trails, and steep ridgelines.

The iconic venue—used in Lost, Pearl Harbor, and Hawaii Five-0—adds Hollywood drama to the challenge. Finishers earn medals, a Trifecta wedge, and a festival atmosphere with music and camaraderie. Racers can compete as teams for shared start waves and post-race celebrations. Visit the organization's website for the most recent information.
