Are you a trailrunner? The American Trail Running Association (ATRA) was formed in 1996 as a Colorado non-profit corporation. We were formed to serve a young and growing trail running community. Our mission is to represent and promote safe, fun and sustainable mountain, ultra and trail running.

ATRA has the largest trail race only event calendar on the web. We also offer individual, club, race and corporate memberships. One of our primary benefits is our quarterly newsletter, Trail Times. Trail Times includes information about upcoming trail running events, thoughtful articles, and news about our sport.
