Sundance to Spearfish Marathon, Spearfish, South Dakota : September 13, 2026
The Sundance to Spearfish Marathon is a point to point road race that runs from Cement Ridge toward Spearfish and passes through parts of the Black Hills of Wyoming and South Dakota. The course is almost entirely downhill except for a sustained climb between mile 2.00 and mile 2.56 that gains 169 ft.
The first 12 miles, from Cement Ridge to Savoy, are on improved gravel roads that run through mountain meadows, valleys, and canyons and descend 1,606 ft. At about mile 9.35 the route passes the winter film site for the movie Dances with Wolves. The remaining 14 miles are on hardtop and follow Spearfish Canyon Highway (Route 14A), a National Scenic Byway, descending another 1,364 ft into Spearfish. That section of the route is shared with the Leading Ladies Marathon.
The course is USATF certified and is listed as a Boston qualifying course. It is one of only two USATF certified courses in Wyoming and may be recorded for either Wyoming or South Dakota. Registration information listed for the marathon shows an entry fee of $141.77 for the period indicated and available spots at the time of posting.
