Course Limits
As a courtesy to the communities impacted by the races and the volunteers who serve, there is a 3 hour limit for the Half Marathon. To finish within this time limit, runners must maintain a pace of approximately 13:44 minutes per mile.
Along the Half Marathon race course, roads will reopen to traffic and water/aid stations will close down as the race moves beyond a 13:44 minute per mile pace. Runners running beyond Course Time Limits are doing so at their own risk. Please be prepared and carry fluids and energy gel throughout the race if pace will be slower than 13:44 minute mile.
Race staff will begin breaking down the finish line after course limits. Runners who finish after limits and are not able to collect a finisher medal on site may contact the race office within 48 hours of the event.

Dogs are not allowed at Greenwich Point Park during this event, as it takes place during the park’s in-season period.
