25K Course Description


After leaving the START at the Challis City Park, you will head south on the HWY 93 shoulder for several hundred yards until reaching the 4-wheeler trail next to the highway on the right. Follow the two track trail down for two miles to the Land of the Yankee Fork Interpretive Center. Cut through the parking lot and begin the Lombard Trail System, a two track trail that will lead you for quite some time. Stay on the Lombard Trail for a 4 mile climb, and up to a lower saddle where an informational placard will give you some geographic history of the surrounding area. Continue ~1.5 miles on the Lombard Trail (now cutting along Blue Mountain, side-hill) to the first Aid Station, BIRCH CREEK SADDLE.


After reaching BIRCH CREEK SADDLE, 25K runners will turn around and run for 2 miles back the way you came, past the saddle with the informational placard and down to the next saddle before taking off on a side trail to the left (north) away from the Lombard Trail, heading along the sage ridge, coming out at Garden Creek Road, entering the road leading you down Main Street Challis and to the finish at Challis City Park.
