About this race
About the Ride:
The Summer Trail Trek is a 3-day, 109-mile supported bicycle ride through the heart of the Black Hills on the George S. Mickelson Trail, a former railroad bed that has been resurfaced with crushed limestone.. This ride offers a fantastic opportunity to experience the beauty of the Black Hills in a way that can't be seen from the road. Participants will journey through four hard rock tunnels, cross over 100 trestle bridges, and traverse several picturesque areas, creating unforgettable memories.
While most of the trail maintains a manageable grade of no more than 4%, some sections are considered strenuous. The highest point is Dumont, with the 10-mile stretch from Rochford to Dumont being the longest incline.
