We thank the following sponsors for making the Butte 100 possible. Whether local or national, we ask our participants and fans to look to these sponsors first for the services or products they provide. We truly could not host “the toughest mountain bike race in the country” without all of these generous organizations and people. Our most sincere thanks to all of you!

Peter M. Sorini M.D.
