ROSEBUD 100 Mile Challenge- Boys and Girls Club of Rosebud

The Rosebud 100 Mile Challenge is a virtual 100-mile event based in Jefferson, Wisconsin, covering 160.9 km. It is designed as a shared challenge for participants and their horses, with a field limit of 400 people. Registration closes once this limit is met. The race supports young people on the Rosebud Reservation in Mission, South Dakota. Each entry donates $5 directly to the Boys & Girls Club of Rosebud, with additional donations possible at checkout. The club states it is the reservation’s sole afterschool program and its only center-based, mentoring-focused youth program. The event features main artwork by AmyLyn Bihrle, providing a distinct visual identity connected to its fundraising goal.
