American Trail Running Association (ATRA)

The American Trail Running Association, ATRA, was formed in mid-1996 as a Colorado not for profit corporation to serve the mountain, ultra & trail (MUT) running community. Its mission is to represent and promote mountain, ultra & trail running.

CamelBak works with ATRA to fund the organization’s trail ambassador program—an initiative that recognizes runners around the country who are doing amazing things to build trail running connections in their communities. You can head over to the ATRA website to see the full list of ambassadors.
