Project 17 of the Greater Yellowstone Adventure Series has a singular goal. This is to steadily and consistently lower the number of daily suicides among American veterans (17.5 deaths per day) to that of the non-veteran population of the United States. It will do this by promoting athletic training programs for veterans that culminate in them taking part in one or more GYAS sporting events in Southwest Montana.

15th Annual Madison Triathlon

10th Annual Tour de Gravelly

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.
