  1. 01What not to do

What not to do

Do not pick a corner from an old map and call it 2027. The FAQ does not name cheer zones. The course-map link in the old record was not the page we used.

Laflin between Adams and Jackson is the only mid-course street with miles on the participant page, and it is a lactation tent.

Ready-made plans

Laflin, then the finish street

Adult support crew

The only mid-course street with a mile on the participant page is a tent, and that page still contains 2026 dates elsewhere.

  1. Mile 15

    Laflin Street

    The participant page does not name a CTA stop here.

    Lactation tent on Laflin between Adams and Jackson at miles 15 and 16. The FAQ says 20 aid stations, about one to two miles apart, and does not name their streets.

  2. Mile 26.2

    Columbus Drive south of Balbo Drive

    The FAQ recommends the CTA and does not name a station for the mat.

    Finish location from the FAQ. Grant Park opens to spectators at 9:30 a.m., so the 7:35 wave is not a viewing plan inside the park.

Meetup: Do not invent a Lincoln Park corner. It was not on these pages.

27th Mile party

Family

The reunion is a party with a clock, not a course mile.

  1. Mile 26.2

    27th Mile Post-Race Party

    CTA is the FAQ's race-day advice. No station is named for the party.

    Sunday 10 October 2027 schedule: party 9:30 a.m. to 4:00 p.m. Times subject to change. Mile field is the finish, because 27 is not a course mile.

Meetup: Gear check closes at 4:00 p.m. the same day, on that schedule.
