Eighth Annual | Olympic Distance Triathlon

Unfortunate News: The 2021 edition of the Polson Triathlon will be the last, at least for the next several years. I thought we offered a high quality event, and we always had incredible sponsorship, community and volunteer support, but the number of participants has continued to diminish. I was hoping 2021 would see a resurgence, but instead we had another tiny group of individual finishers. In my mind, this minimal level of participation just doesn’t justify the multiple weeks of time sacrifices necessary to coordinate all aspects of the event. Some folks have said that the course was just too hard (choppy swim, rough bike surface, hilly run) so it is possible that we will return with a more user friendly version in the future, but that could take a few years. I want to again thank all of the heroic participants, inspiring volunteers and generous sponsors who made this event so special every year. Sorry to not have the available time and energy to keep it going. Matt
