One of the six World Marathon Majors — a flat, fast loop through 29 Chicago neighborhoods.
What you need to know
Chicago Marathon 2027 takes place on Oct 10, 2027, in Chicago, Illinois. The Pilsen and Chinatown stretches near the 30K mark are where runners need crowds most and where the neighborhood energy is strongest — locals skip the packed start line and head straight there.
The Chicago Marathon is one of the six World Marathon Majors, sending a massive field on a famously flat loop through the city's neighborhoods from a Grant Park start and finish.
It is set for October 10, 2027 — the second Sunday of October, per the race's published future-event dates (the organizers note dates can change) — and entry for most runners goes through a lottery that opens roughly a year out, so the running plan starts long before the travel plan. For spectating families and runner support crews, an RV base solves marathon weekend's brutal hotel math: downtown rates spike hard around the race. Chicago Northwest KOA in Union (Metra rail access) and Indiana Dunes State Park in Chesterton (South Shore Line) both put you about an hour from the course by train, with no race-morning parking battle. October is prime Midwest fall camping, so 8 weeks of rig lead is smart. Race morning starts cold — often low 40s — and spectators should dress for standing, not running.
Safety rules and an insider tip
Safety + legal. Course crossings close for hours on race morning — plan which side of the loop your viewing spots are on before you commit, and layer for a cold standing start.
