For cyclists with a competitive side, Spearfish is home to three nationally-known races: 28 Below, Pine Island Gravel Odyssey, and the Dakota Five-O. Each of these races are aimed for different types of cycling from single-track mountain biking and gravel grinding to winter fat biking.
As the premier mountain bike race of the Black Hills, the Dakota Five-O continues to entice riders from across the country. From the pristine, hand-built single-track that graces much of the course, to the PBR and bacon station and the high spirited after party, riders are impressed with this 50-mile race that they continue to return year after year.
Find it and grind it as you take part in the best annual gravel bicycle race in the Black Hills! These races aren't for the feint-hearted and only experienced gravel riders are encouraged to ride! Held in June, riders choose from three races in this annual event: Gold Dust, 70-mile; Gold Rush, 110-mile; and The Motherlode, 210-mile. LEARN MORE>>
The 28 Below Fatbike race is a 50k lolly-pop loop with around 2,800 ft of climbing. It is the only race in the Black Hills that is permitted to take place on groomed snowmobile trail. Although the race takes place in mid March, the snow conditions tend to hold in the high country of the hills. LEARN MORE>>
