Get ready for the exhilarating Mattapoisett Lions Triathlon on Sunday, July 27, 2025, in the picturesque town of Mattapoisett, Plymouth! This exciting event is perfect for both beginners and seasoned triathletes, offering a stunning venue along with enhanced organization thanks to the support of local triathletes. Participants can look forward to a fantastic race day experience, with various distances to challenge and inspire athletes of all levels.

This year, the event has made it easier for non-licensed racers by dropping the USAT sanction, saving you from the additional one-day license fee. Plus, if you're part of a triathlon team, take advantage of a special group discount for ten or more racers! Remember, all proceeds from the event will benefit the Mattapoisett Lions Club charities. Don’t miss out on early registration to avoid the $5 fee increase after July 1. Join us for a day of fun, fitness, and community spirit!
