About This Event

Formerly the Gold Rush Gravel Grinder, this South Dakota gravel event operates under special use permit in the Black Hills National Forest. Ridge Rider Racing has created three distinct routes that showcase the region’s dramatic terrain, from open prairie to deep forest climbs and spectacular canyon vistas.

The flagship Ponderosa Escapade covers 100 miles with 5,600 feet of elevation gain through a challenging single loop. Riders tackle mostly gravel and dirt roads that wind through beautiful canyons with flowing creeks, climb to mountain vistas, and cross into Wyoming. The course demands riders comfortable averaging at least ten mph on technical gravel terrain. A 6:30 am start includes a five-mile neutral rollout from Spearfish City Park before hitting the gravel proper.

Three strategically placed aid stations provide water, food, and Heed sports drink at miles 32, 55, and 72, with specific cutoff times ranging from 9:45 am to 3:45 pm. The mile 55 checkpoint at Trailhead Lodge allows support crew access, making this stop particularly valuable for restocking and mechanical support.

The 65-mile Limber Excursion offers 4,300 feet of climbing with two aid stations, while the 45-mile Pine Cone Frolic focuses on completion over competition with 3,000 feet of gain. The shortest route uniquely allows e-bikes and emphasizes the satisfaction of finishing rather than racing.

All routes reward finishers who make cutoffs with completion awards. The courses blend technical gravel challenges with the Black Hills’ stunning natural beauty, creating an event that tests endurance while delivering memorable scenery through some of the Midwest’s most distinctive terrain.

The Dakota Five-O, held in early Fall in Spearfish, South Dakota, is a legendary 50-mile mountain bike race known for its adrenaline-pumping course. It features an astonishing 90% singletrack, over 6500 feet of climbing, and technical sections that demand true grit and skill from participants. The race starts with a mass rollout from Spearfish City Park, and the course direction alternates yearly, keeping the challenge fresh for returning competitors. The event is celebrated for the race and the weekend-long festivities that include live music, a pre-race party, and a post-race celebration, making it a cornerstone event in the Midwest’s mountain biking calendar​​​.

On the other hand, the Pine Island Gravel Odyssey, formerly known as the Gold Rush Gravel Grinder, is South Dakota’s premier gravel cycling event. Taking place in the majestic Black Hills National Forest under a special use permit, this event offers four distinct route options to accommodate a wide range of cyclists. It’s hailed as one of the Best Gravel Grinders in the Midwest by Strambecco, underlining its significance in the gravel cycling community for its challenging routes and breathtaking scenery​.
