NEW LOCATION FOR 2021 - MARSH POST 442

June 3rd  |  June 17th  |  July 8th  |  Aug 5th  |  Aug 19th  |  Sep 2nd  |  Sep 16th
ALL DATES TENTATIVELY APPROVED, PENDING FINAL DCR APPROVAL

Join us on seven Thursday evenings from June through September for fun, friendly, chip-timed 5K runs to kick cancer’s butt. Each (of the first six dates) starts with a Women’s 5K, followed by the Open 5K ~30 minutes later. (no Women's 5K on Sep. 16th)

All races are held at a new location, the American Legion Marsh Post #442 in Cambridge, MA, and run on paths along the Charles River. Each event will include a post-race party at the Marsh Post with beer generously provided by Mighty Squirrel. 100% of the event proceeds go to charity, including a portion to the American Legion Marsh Post. RACE Cancer Foundation’s Boston 5K Summer Series also provides funding for the Sunscreen Squad, bringing free sunscreen to outdoor events across Massachusetts.
