RACE DAY is Sunday, July 31, 2016.


Registration changes, deferral requests, or other edits will not be accepted via email after Friday, July 22.  Edits such as changing categories, updating information such as date of birth, etc., can be made in person after July 22 at one of the three scheduled race packet pickups.

We strive to provide everyone their requested t-shirt size, but they are ordered weeks in advance.  If you register after July 22, 2016,  we cannot guarantee your requested size will be available on race day. After packet pickup closes on race morning, you can try to exchange your shirt for a different size with what is leftover.  Thank you for understanding.

Unfortunately, we do not provide refunds.

Announcing the Inaugural KIDS SPLASH & DASH!

We are excited to host kids, ages 7-15 in the first ever Boston Tri Kids Race. Taking place at Carson Beach after the adult race wraps up, the Boston SPLASH & DASH will consist of a swim followed by a run. There will be four different age groups:

Ages 7-8 and Ages 9-10: Swim 100 yards, Run 1K

Ages 11-12 and Ages 13-14: Swim 200 yards, Run 2K

The swimming will take place along the beach near the McCormack Bathhouse and will be in shallow water. The run will be on the Harborwalk Trail.

The entry fee is $35 (or $25 if the child is an annual USAT member).
