Sweep buses will follow the marathon route at a 6 1/2-hour marathon pace, roughly 15 minutes per mile, after the final wave start. These buses will transport any entrant who wishes to drop out to the post-finish area. After the sweep buses pass, the city streets will reopen to traffic. Cross-street protection, medical assistance, aid stations, and other services will no longer be available. Runners on the course should move onto the sidewalks. The official end time of the race is 7:25 p.m.
