Annual Dakota Five-O

The Dakota Five-O is a mountain bike race that is not for the weary. With a challenging track, it is a fun event that starts in Spearfish and has different trails for different riders. The Dakota Five-O continues to entice riders from across the country. From the pristine, hand-built singletrack that graces much of the course, to the high spirited after party, riders are impressed with the event. The start/finish is at the Spearfish City Park, which is also the location of the Pre Party 5-9 p.m. on Friday and the After Party and Award Ceremony 11 a.m.-5 p.m. on Sunday. 2025 marked the 25th anniversary.
