The Boston Triathlon is a marquee summer sporting event, taking over South Boston's Carson Beach for sprint and Olympic-distance racing alongside a nationally recognized Kids Day for hundreds of local youth. The race draws 10,000 attendees and airs across WCVB, NECN, and NBC10. The event holds an even 50/50 gender balance, along with racial and socioeconomic inclusivity and year-round programming designed to remove barriers to entry in endurance sports. In 2024, the event drove an estimated 93M impressions and over $1B in earned media reach, and continues to grow through its alignment with the international Supertri series, an ideal fit for brands seeking a nationally covered race with deep community roots.
