The mission of the Greater Yellowstone Adventure Series is to invite athletes, explorers, and adventurers from around the world to the high mountains of Southwest Montana and provide them with the penultimate race experience.
Twenty years from now you will be more disappointed by the things you didn't do than by the ones you did. So throw off the bowlines, sail away from the safe harbor. Catch the trade winds in your sails. Explore. Dream. Discover.
