Join us for the 5th  annual Charles River Marathon on October 31st, 2021. This flat, fast BQ-eligible course attracts runners from across the United States and overseas to Boston's beautiful Herter Park. Over 47% of finishers in the 2017 Charles River Marathon qualified for the Boston Marathon.

The marathon course is USATF-certified and thus eligible as a qualifier for the Boston Marathon. 100% of the proceeds of this event benefit RACE Cancer Foundation and its 501(c)(3) partners.

Race entry capped at 300 runners.
The marathon course is a flat 2.62 mile loop on paved paths around Boston's scenic Charles River, starting and finishing at the DCR’s Herter Park in Boston, MA. Marathon runners will complete ten laps (26.2 miles) of the course. The marathon will be held on a USATF-certified course, eligible as a qualifier for the 2021 Boston Marathon.
