Goat Rattler 100 - Ogden, Utah
Goat Rattler 100 is a trail ultramarathon held in Ogden, Utah on June 25 to 26 2027. The primary course is listed as 101.5 miles with approximately 22,500 feet of elevation gain and about 96% singletrack. Registration opens on 11/1/2026.
The course uses no continuous markings; competitors are expected to follow a GPX file on a watch or phone. Directional signs will be placed at intersections or where the route doubles back. Organizers state this choice is to reduce trail litter and follow leave no trace principles.
Every runner will carry a Garmin In-Reach device for live GPS tracking so crews can follow progress in real time. A short vehicle shuttle is required at mile 48.8 to cross Pineview dam; the shuttle covers roughly 1.5 miles to windsurfer beach and runners rejoin the route at the shuttle exit.
There are no formal prerequisites listed for entry, and the organizer notes caution for first time 100 mile participants. Refund and transfer policies are specified: a full refund is available for withdrawals by 3/31/25; a partial refund of $150 is available from 4/1 to 5/1/26; after that, refunds are generally not offered. Rollovers and bib transfers are not permitted. Finishers receive a belt buckle and event merchandise. Event sponsors include Ogden Running Company and Speedland.
