The Bank of America Chicago Marathon is one of the six World Marathon Majors, attracting elite athletes and amateur runners from around the globe. As the 2025 edition approaches, participants and spectators alike are eager to know the details that will make race day a success. This comprehensive guide covers everything from race-day apparel to start times, tracking options, and prize money.
Apparel: What to Wear for the Chicago Marathon
Choosing the right apparel is crucial for comfort and performance during the marathon. Here’s what to consider:
1. Technical Fabrics
Opt for moisture-wicking materials like polyester or nylon to keep sweat away from your skin. Avoid cotton, as it retains moisture and can cause chafing.
2. Layering
Chicago’s October weather can be unpredictable. Layering allows you to adjust to changing temperatures. Start with a light base layer, add a long-sleeve shirt, and top it with a windbreaker or light jacket.
3. Compression Gear
Compression socks or sleeves can improve circulation and reduce muscle fatigue. They’re particularly beneficial for long-distance runners.
4. Footwear
Choose well-fitted running shoes that you’ve broken in during training. Avoid new shoes on race day to prevent blisters.
5. Accessories
-
Hat or Visor: Protects against sun and rain.
-
Sunglasses: Shield your eyes from UV rays.
-
Gloves: Useful for early morning starts.
-
Hydration Belt: If you prefer carrying your own fluids.
Remember, comfort is key. Test your gear during training to ensure it works well for you.
