Beartooth La Femme

A women's-only bike tour on Beartooth Pass, this 62-mile out-and-back starts and finishes in Red Lodge. It's not set up as a race, but there will be an award for the first to the top (i.e., the halfway mark). There are no timing chips, but there will be rest stops with snacks and hydration along the way. Dinner the night prior to the ride and breakfast the morning of are included in your race fee. If you're coming from out of town, check out the "Deluxe" registration option, which includes a room at the Pollard Hotel.
