Boise Spartan Trifecta Weekend

Boise Spartan Trifecta Weekend returns to Tom Pence Ranch in Payette, Idaho, on Aug 8–9, 2026. The event offers three Spartan distances: Sprint (5K/20 obstacles), Super (10K/25 obstacles) on Aug 9, and Beast (21K/30 obstacles) on Aug 8, plus a Kids Race. Set in Western Idaho’s rugged high desert with Snake River Plain scenery, the course features steep climbs, deep dust, and off-road terrain alongside classic Spartan obstacles such as Atlas Carry, A-frame Cargo, Barbed Wire Crawl, Rope Climb, Multi-Rig, Spear Throw, and more.

Expect a festival atmosphere with finish-line energy, music, and beer gardens. Team signups unlock synchronized starts; Trifecta medals await those stacking challenges. Visit the organization's website for the most recent information.
