Chicago runs on October 10, 2027. Apply by October 29, 2026, at 2 p.m. US Central; drawing results arrive December 8. Non-charity entry costs $250 for US residents or $260 internationally, plus processing. The flat city course is the appeal, but a ballot application is no bib. Keep travel refundable and treat the previous route as a reference until the 2027 guide is published.

Major race decision brief
Know the catch before you book the flight.
Four facts shape this weekend: entry, course load, the start-to-finish problem, and whether your crew gets a good trip too.
01 · Secure the bib
Ballot open
Non-charity entry: $250 US / $260 international, plus processing. Applications close October 29 at 2 p.m. US Central; drawing results December 8. Charity fees and fundraising are separate. Treat travel as refundable until your place and any qualification requirement are confirmed.
02 · Read the load
57 m climbing
Chicago has historically used a flat city loop starting and finishing in Grant Park. The 57 m climbing estimate and venue pins are previous-edition references. Confirm the final 2027 course, expo location and access controls before using them for pacing or travel.
03 · Solve the base
Compact race geography
Start and finish sit within roughly 1 km. A central base can simplify race morning and reunion, but road closures still decide the useful side of the course.
04 · Pack the range
9–17°C
Historical rain signal: 25%. Use reviewed climate data for packing, then switch to the live forecast inside race week.
Crew fit is 5/5. Use the spectator guide to decide whether this is a shared city weekend or a runner-first operation.
Why we'd pick it
- The 57 m climbing estimate is useful for planning, not a verified pacing number.
- The ballot is open; apply before the published deadline and keep a backup race.
- A non-racing partner gets a real weekend here — 5/5.
- Race day usually sits 9–17°C, about 25% chance of rain.
