2026 Boise Spartan Trifecta Weekend

We’re heading back to Western Idaho’s rugged high desert, where the Snake River Plain carves through sweeping vistas and volcanic soil. Pence Ranch—an athlete favorite—brings raw, untamed terrain and wide-open skies that demand your full grit. Expect steep climbs, deep dust, and a Trifecta weekend packed with signature Spartan intensity. Whether you're chasing your first medal or stacking another Trifecta, Boise delivers the challenge—and the scenery—you won’t forget.
