That spike in runners along the Lakefront Trail that is guilting you during every morning commute can mean only one thing: The 36th annual Chicago Marathon is fast approaching. Here’s what you need to know before the participants pound the pavement for 26.2 miles on October 13.

  • 45,000 registered participants
  • 2:04:38 course record

  • 10,212 international runners
  • 77,760 gallons of water and 1.1 million Gatorade cups
  • 1,500 portable toilets

Security changes for this year: Runners must pick up their own bib packets; no one may pick up a bib packet on behalf of a runner. Only transparent event-issued bags allowed in Grant Park and accepted at the gear check.
