Salt and Sulfur 420

Salt Lake City, United States • 5 Aug 2026

Salt and Sulfur 420 is a 420-mile endurance journey from Salt Lake City, Utah, to West Yellowstone. The event blends ultrarunning with personal growth, emphasizing mental fortitude as much as physical stamina. Runners traverse mostly paved roads with about 50 miles of dirt, along a rugged, scenic corridor through Utah and Idaho.

Described as a crewed, community-focused experience, it centers on adventure, connection to nature, and self-discovery, with all proceeds donated to the Women’s Center in Salt Lake City. The atmosphere is intense, with the run viewed as roughly 20% physical and 80% mental—not for everyone. A testament to resilience and mindset.
