2026 Boston Triathlon

The Boston Triathlon is a marquee summer sporting event that combines elite competition with a deep civic mission.

Now in its 18th year, this iconic race weekend takes over South Boston’s Carson Beach for a one-of-a-kind experience rooted in sport, community, and culture.

Held over two days, the event features:

• Sprint and Olympic-distance triathlons for individuals and teams
• A nationally recognized Kids Day with free events for hundreds of local youth
• A full weekend of training, celebration, and media engagement

The Boston Tri has earned a reputation for its 50/50 gender balance, racial and socioeconomic inclusivity, and year-round programming designed to remove barriers to entry in endurance sports.

It’s a unique sponsorship opportunity: a nationally covered race in a major market with deep roots in community impact and youth development.

In 2024, the event drove 93M+ impressions, 1B+ in earned media reach, and continues to grow through its alignment with the international Supertri series.
