Event overview
The Goat Rattler 100 is a 100-mile ultramarathon held in North Ogden, Utah. The start line is at McGriff Park (2950 N 900 E, North Ogden). Registration for the 2026 event opens on 12/1/2025 and will remain open until filled, with a wait list if necessary. Entry fee is $399 plus tax and an Ultrasignup fee. The race uses a 36-hour cutoff.
Course and race logistics
The course is reported to be about 97% single track with 22k of elevation gain and extensive views of the Wasatch mountains. Live GPS tracking will be provided. Aid stations will offer upgraded nutrition, some locations have limited parking and holding areas for crew, and camping at Cutler Flats is included through Sunday. Crews are allowed but must follow race rules; first-aid pickup for a pacer is at Green Pond (mile 33.4). The event has an official permit and prior results count toward future qualifying races. Registration materials note a refund policy and that the full policy is available on the event website. For 2026 there is no race-qualification requirement, and the event organizer advises it is not intended as a first 100-mile race. Visit the organization's website for the most recent information.
