Charles River Marathon Invitational

Sun September 7, 2025 Boston, MA 02134 US Directions

Bike Marshals (must bring your own helmet & bike)

Bike marshals assist with final prep and review of the race course before the race. During the race, some bike marshals ride 1-2 minutes ahead of the field, while others ride alongside race leaders and vulnerable groups of runners to help ensure their safety. Bike marshals should be prepared to dismount their bike and assist on foot, so cleated shoes are not recommended.
