Chicago is built for even splits. The flat course and ideal October weather make it perfect for locking into goal pace from the start. Don't go out too fast - the lack of hills means no excuses.
| Miles | Terrain | Advice |
|---|---|---|
| 1-5 | Flat (Loop north) | Easy to go out fast. Stick to goal pace. The crowd energy in Lincoln Park is incredible. |
| 6-10 | Flat (North side) | Settle into rhythm. Boystown crowds at mile 8-9 are legendary. |
| 11-15 | Flat (West loop) | Halfway point. Check in with your body. Maintain form. |
| 16-20 | Flat (South/Pilsen) | This is where flat becomes mentally tough. Stay focused. Crowds thin slightly. |
| 21-23 | Flat (Chinatown) | Dig deep. The dragons and drums in Chinatown will lift you. |
| 24-26 | Flat (Michigan Ave) | Final push on Michigan Ave. Trust your training. PR awaits. |
Standard fueling works well on this flat course. Take gels every 45-60 minutes. The predictable pace makes it easy to plan exact timing. Don't experiment on race day.
Yes! Chicago is one of the fastest courses in the world with only 89m of elevation gain. The flat terrain, great weather, and crowd support make it ideal for personal bests.
Chicago has just 89m (292ft) of elevation gain - essentially pancake flat. The only 'hills' are highway overpasses that feel like speed bumps.
October in Chicago typically offers ideal marathon conditions: 7-15°C (45-60°F), low humidity. Occasionally it can be warm or windy off the lake.
Chicago is the fastest of the World Marathon Majors due to its flat course. It's easier than Boston, NYC, and Tokyo. Similar to Berlin in terms of PR potential.
