Salt and Sulfur 420
Salt and Sulfur 420 is a crewed running event scheduled for August 4, 2027. The route starts in Salt Lake City, Utah, and finishes in West Yellowstone, covering a total distance of 420 miles.
The course follows primarily paved roads with approximately 50 miles on dirt surfaces. The route crosses varied terrain and conditions that require sustained effort and planning. The event emphasizes a connection to nature and personal development through extended time on the route.
The organizer describes the effort as mentally demanding after multiple days on the route; selection is limited and not all applicants will be accepted. The event directs proceeds to a local charity, with all net proceeds donated to the Women’s Center in Salt Lake City.
Registration for the event closes June 1. Additional event details include its crewed format and the point-to-point course between Salt Lake City and West Yellowstone. Visit the organization's website for the most recent information.
