The Oct. 19 Marine Corps Marathon could be canceled because of the government shutdown, organizers said Tuesday.
Runners will be notified by this Saturday, Oct. 19, if the event is going to be affected.
Around 30,000 runners from around the world participate in the annual marathon, which weaves through federal properties in Washington, D.C. that are closed because of the shutdown.
Runners paid $99 to enter this year's Marine Corps Marathon, and entry slots sold out in a matter of hours.
Organizers said they were still working on the details of how to handle a cancellation and now to reimburse entrants if it doesn't take place.
