Contact Details

The Greater Yellowstone Adventure Series races are held on public land in Madison County in Southwest Montana.  The race routes are all part of the Greater Yellowstone Ecosystem.  The GYAS is headquartered in Ennis, Montana, but the race directors live around the world.  Ennis is a small town about 50 miles west of Bozeman and 70 miles north of Yellowstone Park.  Race Director Sam Korsmoe is a vagabond of sorts. He could be in Ennis, Bozeman, Helena, New York, Saigon, or Shanghai.  It’s a work thing that he has going on.  Race Director Colter Korsmoe is also a vagabond of sorts, but he’s a student studying Mechanical Engineering at the University of Michigan.
