Much like the CTR, the AZT, and the Tour Divide, the Black Hills Expedition is a self-supported, self-timed ITT (Individual Time Trial) bikepacking race. We provide a route description and GPX file, a suggested start time, and a list of results. There is no registration, no entry fee, and no support.

This route takes riders on a whirlwind tour of the area’s most famous attractions like Mount Rushmore, Custer State Park, and the Crazy Horse Memorial.
