You Are Not at the Top of the Food Chain Here, so Better Run Fast!!
That's right: The Wolf, the Coyote, the Fox, the Bear, the Cougar: you are not at the top of the food chain here, so Run Fast.
With a start and finish in Challis, Idaho, the River of No Return (RONR) Endurance Runs offer runners a unique opportunity to experience Idaho’s beauty.
Choose between distances of 32k, 55k, or 108k, where you’ll be challenged by varying terrain and awed by gorgeous scenery.
Designed to be tough and beautiful, the courses tour some big mountain climbs over 9000 feet. Elk, deer, eagles, bears and wolves add to the mystique of the River of No Return, as do the forgotten mines and mining communities, old Idaho traditions – all surrounded by the very supportive community of Challis.
Runners will be treated to a fast finish down Main Street Challis and back to the Challis City Park. Enjoy the return to civilization in the last mile as the locals cheer you home!
The course is crew-friendly with multiple aid stations that are support team-accessible without the use of four-wheel drive vehicles.
THE 55K & 108K START AND FINISH AT THE CHALLIS CITY PARK, right next to the High School. THE 32K STARTS AT THE GHOST TOWN OF BAYHORSE AND FINISHES AT THE CITY PARK
Once taking off from the Park 55K & 108K runners cross Main Street - Challis, and onto an ATV trail, all runners will quickly be guided into remote country by mile 2.5 and all races will traverse the initial 9 miles along the same route. Spectators and fans will see runners barrel the final mile down Main Street - Challis before re-entering the City Park for a warm welcome home. Runners are allowed to have crew and fans complete the final run down Main Street to the Finish with them.
108K has about 17,600' elevation gain and 9 aid stations. It is a large, single-loop course that has five significant climbs, cresting 8000', 9000', and 10,000'. The majority of the course is on two-track (meaning ATV width trail), with a few miles of dirt road, about 8 miles of single track trail, and 5 miles of pavement at the finish coming into Challis. Start is 5:00 am, and you have 22 hours to complete the course, with some intermediate cutoffs along the way.
55K has about 8800' elevation gain and 5 aid stations. Courses provide runners with three major climbs that take runners over 8000' and is mostly narrow ATV trail, some dirt road, single track elk trails and some pavement that will bring runners to the finish in Challis. It is a large lollipop-type loop, with a 3.5 mile down from Keystone Aid Station to the old Ghost Town of Bayhorse, and a partial return with an added climb in a loop back to Keystone. Runners now return via the Lombard Trail to Birch Creek Saddle and finish via the 32K course elk trails and a mile run down Main Street. Start is 6:30 am, and runners have 12 hours to complete the course.
32K has about 4500' elevation gain and 2 aid stations. The race starts at Bayhorse and is a point to point return to the Challis City Park following the 55K route.. The Start is 9:00 am.

RONR highly encourages the use of support crews, especially in the 55K and 108K races. Although we will have fully stocked and top-notch aid stations that will make each runner feel like an 'elite' competitor, we want your family and friends to get to experience some of Idaho's beauty too. Crews will be treated to gorgeous drives along the Salmon River as they make their way to the various aid stations.
Crews in the 55K will be able to support their runners at Bayhorse (Mile 16), as well as running with their runners down Main Street Challis and onto the Track. No pacing, though, for 55k runners at any other point along the course.
Crews in the 108K will be able to catch their runners at Bayhorse (16M), Bayhorse Lake (36.5M), Squaw Creek TH (45.6M), and Custer Motorway (61.7M), as well as running with them down Main Street. 108K runners may pick up a pacer after mile 36.5, Bayhorse Lake.
No Crews in the 32K - force your crew to register and run the 32K with you !!!!!
