CHICAGO (CBS) — Time is running out if you want to get a guaranteed slot in next year’s Chicago Marathon.

Thursday, Nov. 30 is the deadline to apply for a slot in the 2018 Chicago Marathon. Runners who can finish the course in a certain time or runners who are tackling their fifth Chicago Marathon in 10 years are eligible for a guaranteed entry. And perhaps the easiest way to get a guaranteed space in Grant Park next October is to run with a charity team.
