Registration for the 2020 Columbia Threadneedle Investments Boston Triathlon is now open!


RACE DAY is scheduled for Sunday, August 2, 2020.

Registration changes will not be accepted via email after Friday, July 31.  Edits such as changing categories, updating information such as date of birth, etc., can be made in person after July 31 at one of the 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 17th, 2020,  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, nor deferrals.
