OUR SPRING & SUMMER SERIES RETURN TO THE MARSH POST WITH EIGHT RACES IN 2026!
TENTATIVE DATES: 4/30, 5/21, 6/4, 6/18 - 7/9, 8/7, 9/10, 9/24
Join us on eight Thursday evenings from April through September for fun, friendly, chip-timed 5K runs to kick cancer’s butt. The first four dates will start with a Women’s 5K, followed by the Open 5K ~30 minutes later. Everyone races together in the final four races of the series.
All races are held at 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.
