Chicago Marathon Fueling Guide: Nutrition Tips for Race Day Success
Every October, tens of thousands line up in Grant Park to run the Chicago Marathon. Flat, fast, and iconic โ but only if your fueling is on point. Hereโs how to dial in your race-day nutrition with clean, natural products.
๐ Why Fueling Matters in Chicago
- Flat & fast course: requires steady carb intake to avoid the wall
- Unpredictable weather: Chicago can be 40ยฐF or 75ยฐF on race day
- Big crowds & aid stations: plan gels between stations, not just at them
โก How Many Carbs Do You Need?
Most marathoners perform best with 60โ90 g of carbs per hour. Thatโs usually 2โ3 gels every 45 minutes, plus hydration.
Pro tip: Train your gut weeks in advance by practicing your fueling at race pace.
๐ฅ Best Energy Gels for the Chicago Marathon

- Untapped Maple โ simple maple syrup fuel, great for sensitive stomachs
