About this race
Chicago's near-sea-level course and minimal elevation change make it consistently one of the fastest World Majors. The loop format — starting and finishing at Grant Park — takes runners through 29 distinct neighbourhoods, each with its own character: the noise of Wrigleyville, the energy of Pilsen, the polish of Lincoln Park. October temperatures are typically ideal for fast running (10–18°C at the gun), and the flat profile allows runners to settle into goal pace from the first kilometre. The lottery fields roughly 45,000 runners from hundreds of countries. For Americans chasing a Boston qualifier, Chicago is often the most accessible route — ample charity places are available for those who miss the lottery. Mile 18 through Chinatown is famous for the deafening noise and drumlines.

- Chinatown around mile 21 is a lift when it hurts most — use the crowd.
- Save a little for the short Roosevelt Road rise just before the Grant Park finish.
