The Charles River Swimming Club was founded in 2005 with the dual purpose of organizing competitive swimming events in the Charles River and facilitating the return of public river swimming. Our main event is an annual one mile swim in the Charles’ basin.

After decades of pollution, the Charles River has benefited from the ongoing Clean Charles River Initiative, which was started in 1995 to restore the river’s ecological health. The river is now clean enough on most summer days to meet swimming standards. The club aims to raise awareness of and celebrate the efforts that went into cleaning the river, as well as to highlight the need for continued clean-up to enable recreational swimming in the future.

The race is on!  Water quality tests were excellent.  See you at the dock bright and early!
The 2016 swim will take place on June 11 with a rain date of June 19. Registration is now closed, please consider coming out to cheer! Please also sign up for our mailing list for ongoing updates about our swim and club!
