In early autumn, the town of Spearfish, South Dakota, is overtaken by the Dakota Five-O 2025. This adrenaline-pumping mountain bike race promises 50 challenging miles of intense riding, enticing not only with its distance but also with its technical complexity. This is not a race for the faint of heart or the casual biker – it requires true grit, as the race encompasses about 90% singletrack, a daunting 6500+ ft of climbing, and treacherous technical sections. Riders enjoy the incredible single track, big crowds with many riders, and good event organization.
