Celebrating Long Lives 5K Boston, MA   May 10, 2025

For the past three years, CLL Society has hosted a national, virtual 5K walk/run fundraiser. In 2025, for the first time, this event will also have an in-person component located at Millennium Park in West Roxbury, MA combined with a picnic so that CLL patients and their families can meet others in the area.

Participants of all ages will have the option to walk or run 5 kilometers on a loop track within Millenium Park, or join the picnic and show support for those who are doing the 5K. 

No matter your connection to chronic lymphocytic leukemia or small lymphocytic lymphoma (CLL / SLL), your participation supports the work of CLL Society to improve the quality and longevity of the lives of all those impacted by CLL / SLL.
