Registration opens for Chicago Marathon in 2017

CHICAGO (WLS) -- It's already time to start getting ready for next year's Chicago Marathon.

Registration is now open for guaranteed entries, which means a runner had a qualifying time in a certified marathon since the start of last year.

Runners are also eligible if they've taken part in five of the last 10 Chicago Marathons or if you are running for a charity.
