Race information

The Boise Spartan Trifecta Weekend 2026 takes place in the rugged high desert of Western Idaho, where the Snake River Plain cuts through sweeping vistas and volcanic soil. The Pence Ranch, a beloved athlete destination, offers raw, untamed terrain and wide-open skies that demand participants' 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.

You run Tue and Thu (Strava). I kept those and added a Saturday long run building to 2 h, plus a Wednesday grip and carry session. Easy the last two weeks.
