Goat Rattler 100
About the race
Come rattle with us in beautiful Ogden, UT. The course is 97% single track, with 22+k of elevation gain and some of the best views of the Wasatch mountains.
Live GPS tracking through Trackleaders returns, which cuts down on crewing headaches, adds safety in an emergency, and lets family follow along. Raffles include lots of giveaways.
Crewing and pacers
Crews are allowed but must follow race rules, or their runner may be subject to disqualification. Use the tracker and arrive 10 minutes before your runner reaches the aid station to avoid congestion.
Some aid stations have little to no parking, so you cannot camp there all day or night. There are plenty of places to wait that are not the aid station.
The runner's guide on the website has the full details.

Goat Rattle 50 Mile
Benny Goat 55k
Goat Rattler 50 miler
The 50 miler starts Friday evening at 9pm, in the dark. The start line is at the Windsurfer Beach boat ramp at Pineview Reservoir. The cutoff is a generous 18 hours.
The 50 miler crosses the last 50 miles of the 100 mile course, hitting Lewis, Ben Lomond and just below Willard Peaks. The Forest Service does not allow use of the trail up to Willard Peak.
Benny Goat 55k
The Benny Goat 55k gives a taste of the vert and of what the 50 and 100 mile courses are like. It starts Saturday morning at 7am at the Coldwater trailhead in North Ogden. Course map and GPX files are on the website.
The first 2 miles climb around 1400' to the Divide parking lot, where the first aid station is. All aid stations are the same as on the 50 and 100 from the North Ogden divide onward.
No pacers are allowed for this distance.
Requirements and preparation
There is no race requirement to qualify. However, this should not be your first 100 miler unless you want to suffer. Many racers in the 2025 race said it was harder than Bear and many said harder than Wasatch, so take that into consideration.
Come prepared and ready to hit all the peaks along the way.
Course navigation and marking
There is no course marking. The GPX will be available to download and send to your watch. Major intersections and places where the course crosses more than once will be marked.
If you take a few wrong turns, have to double back a couple times, that's just part of the experience.
