Triathlon Races in Massachusetts 2025 - 2026

The Massachusetts triathlon season is pretty short compared to other states being limited from May to September. You’ll still find some incredible races taking advantage of historic city courses alongside beautiful coastal courses. Whether it’s a shorter Super Sprint distance, Sprint distance or Olympic triathlon you’re after or a longer 70.3 or ironman/full distance you’re in the right place. There’s a race for everyone in Massachusetts from city races in Boston to the beautiful backdrops of cape cod.

If you’re new to Triathlons and not sure how to get started, we recommend taking a look at beginner friendly events such as Falmouth triathlon which even has beginner swim waves. Fancy some historic city vibes? Check out the Boston Triathlon, the only race in Boston proper.

If you’re a first timer triathlete starting your journey with a Super Sprint triathlon or a seasoned pro looking for a Double Ironman distance event, you’ll find the most comprehensive list of Triathlons in Massachusetts at findarace.
