The Home of the RONR Endurance Runs

A small town with a big heart, Challis, Idaho is the ideal base camp for Idaho’s premier trail races. Challis is located in the center of Idaho surrounded by recreation on public lands in the White Cloud Mountains, Frank Church River of No Return Wilderness, and Salmon-Challis National Forest.

If you want to make a vacation out of your race weekend, you will find unparalleled fishing, hiking, mountain biking, rockhounding, wildlife viewing, mountaineering, river rafting, hunting, and off-highway trail riding. If you’re a history buff, you’ll be busy for days at the Land of the Yankee Fork Park, North Custer Museum, ghost towns of Custer, Bonanza, Bayhorse and the behemoth gold dredge on the Yankee Fork. Get off the beaten track and trace the trail where wagons carried food and necessary supplies from Challis to the Yankee Fork Mining District by driving the scenic Custer Motorway. Explore Challis by starting a downtown walking tour at the North Custer Museum.

Fly into Boise (BOI), Idaho Falls (IDA), or Sun Valley (SUN) and then rent a car and drive to Challis. You’ll pay a little more for the flight to Idaho Falls or Sun Valley, but the drive is a little shorter. Your call. There’s also a good chance you can connect with some nice runner in one of those localities to rideshare up with too.
