The Ann Arbor Triathlon Club is an organization that promotes participation in triathlon and multisport through organized and informal training, education, volunteering, and social activities. Our membership includes a wide range of people, from individuals who participate for general fitness and socializing, to beginners who are learning about triathlon, to seasoned athletes training to be competitive racers. Although we mainly focus on triathlon (swim-bike-run), many of our members also enjoy participating in a variety of other activities and races, such as road and trail running, road and off-road cycling, duathlon (bike-run), aquathlon (swim-run), aquabike (swim-bike), open-water swimming, swimrun, and adventure races. We are a non-profit group run exclusively by volunteers, and participation in committees is open to all members.
