Where it stands
As of 31 Aug 2026
The 2027 application has not opened: chicagomarathon.com/apply still serves the 2026 cycle only and asks 2027 hopefuls to join the free Mile by Mile newsletter to be told when the window opens.
The 2026 cycle is the benchmark, and it is fully published: applications ran 21 Oct 2025 to 14:00 US Central on 18 Nov 2025, with drawing results emailed 11 Dec 2025, so a 2027 window around late October 2026 and results around early to mid December 2026 is an estimate carried from that cycle rather than an announced date. Applying to the drawing costs nothing; the entry fee (USD 250 for US residents, USD 260 otherwise, at 2026 rates) is charged only if an entry is awarded.
Race day is Sunday 10 Oct 2027, the 49th running.
How to enter
Apply at chicagomarathon.com when the 2027 window opens, either with a guaranteed-entry claim (time qualifier, legacy finisher, Chicago Distance Series, etc.) or as a non-guaranteed drawing application
Your odds
Drawing odds not published and the organizer says the number of drawing entries is not disclosed; a large share of the ~55,000 field (2026 field size per official Dec 2025 press release) goes to guaranteed and program entries: time qualifiers, legacy finishers (5+ Chicago finishes within the last 10 years), Chicago Distance Series, charity entries (USD 2,200 minimum fundraising) and approved international tour operators
Good to know
- The race date is already official even though the application window is not. 10 Oct 2027 is on the organizer's published future event dates page (which notes dates can still change), so travel can be planned around it; the estimate marker here is about when applications open, not about race day.
- One form carries two different routes. Guaranteed-entry claims and non-guaranteed drawing applications go through the same application at chicagomarathon.com, so anyone holding a qualifying time or a legacy claim should enter that way instead of taking their chances in the draw.
