Various marathon events are scheduled to take place, resulting in localized road closures and transportation adjustments.

In Ontario, the 23rd annual County Marathon involves a full marathon, half marathon, relay, and various shorter runs. The event, which begins in Wellington and ends at the Crystal Palace in Picton, requires rolling road closures coordinated by the Ontario Provincial Police across several county roads and Picton Main Street.

In the District of Columbia, the 51st Marine Corps Marathon will necessitate significant changes to public transit and road access. Metrorail plans to open two hours early with increased frequencies on multiple lines, while Metrobus services to the Pentagon will be diverted. Extensive street closures and emergency no-parking zones are expected to affect major thoroughfares, including Independence Avenue and Rock Creek Parkway.
