Welcome to the 10th Annual Santa Speedo Run!

Started in Boston in December 2000 by five intrepid men, the Santa Speedo Run has attracted thousands to run through the streets of Boston all while raising money for local charities, spreading holiday cheer and having a great time. It has also influenced others in many cities across North America to duplicate the event. Have a look around the website to read about how the run was started, to learn the details for this year’s run, and to understand how you can participate or make a donation to support the cause.

This year’s run will once again start from Lir on Boylston Street at 1:00 pm on Saturday, December 12th. We will be running to benefit two terrific local charities that are making huge differences in the lives of youth across Massachusetts – Crossroads for Kids and Bottom Line. Please see the Charity page or visit their websites to learn more.

UPDATE: We have reached our capacity for the 2009 event and are no longer accepting registrations or waitlist applications. If you are interested in being on the Santa Speedo Run mailing list, please send an email to with your first name, last name, and email address and you will be included on email updates about future events. Thank you for your interest and your support.
