Run into the heart of a volcano and come out transformed

Overview

The Spitfire Ultra is not your average trail race. Hosted on the North Menan Butte, the world’s largest tuff cone volcano, this event invites runners to dance along its rim, drop into its crater, and conquer its rugged terrain. It’s a high-energy, early-season challenge designed to light your fire, whether it’s your first trail race or your fiftieth.

From sweeping views of the Tetons to the Snake River winding below, every step feels like a journey through geologic time. The volcanic sand, rocky ridges, and twisting singletrack promise variety, grit, and reward. You’ll climb, descend, and push through technical footing while feeding your fears to the belly of the volcano. By the time you finish, you’ll have left more than footprints—you’ll have transformed. You are Spitfire.
