How to Prevent Chafing During a Marathon

Chafing is a common issue that many runners face during a marathon. It occurs when skin rubs against skin or clothing repeatedly, causing friction that can lead to irritation, redness, and even painful blisters.

Fortunately, several practical strategies and preventive measures help runners avoid chafing during a marathon and have a more comfortable running experience.

1) Choose the Right Clothing

Moisture-wicking fabrics:
One of the most important preventive measures is to wear moisture-wicking clothing. These fabrics help to keep sweat away from the skin, reducing the chance of chafing. Look for running-specific apparel made from materials such as polyester or nylon, as they are designed to effectively draw sweat away from the body.

Proper fit:
Ensure that the clothing you choose fits well. Avoid clothing that is too loose or tight, as both can contribute to chafing. Opt for a snug but comfortable fit that allows for freedom of movement. This will minimize unnecessary rubbing and friction during the marathon.

2) Use Lubricants

Petroleum jelly, anti-chafing balms, and powders:
Lubricants are an effective way to reduce friction and prevent chafing. Various options include petroleum jelly, anti-chafing balms, and powders. Apply the lubricant generously to areas prone to chafing, such as the thighs, underarms, and nipples. This creates a protective barrier between the skin and clothing, reducing friction and minimizing the likelihood of chafing.

Importance of hydration:
Staying adequately hydrated throughout the marathon is essential for various reasons, including reducing the risk of chafing. Dehydration can cause the skin to become dry and more susceptible to friction. Ensure to drink plenty of water and other fluids before, during, and after the marathon. This ensures that the skin remains adequately moisturized, minimizing the likelihood of chafing.

4) Consider Compression Garments

Benefits of compression shorts or tights:
Compression garments provide support to the muscles, reduce muscle vibrations, and improve blood flow. By offering a snug fit, they also help to minimize friction between the skin and clothing. Consider wearing compression shorts or tights as part of your running attire. They can be particularly beneficial during a marathon, as they reduce the risk of chafing and enhance muscle recovery and performance, ultimately contributing to a more enjoyable running experience.

5) Listen to Your Body

Addressing discomfort promptly:
During the marathon, it is essential to listen to your body. If you feel discomfort or notice any signs of chafing, such as redness or irritation, take a moment to address the issue. Add additional lubricant to the affected area or adjust your clothing if necessary. Being proactive in addressing potential chafing can prevent it from escalating into a more severe issue and allow you to continue running comfortably.


Chafing during a marathon can be an uncomfortable and distracting experience for runners. However, by following these preventive measures, you can significantly reduce the risk of chafing and enjoy a more comfortable and enjoyable running experience. Remember to choose moisture-wicking clothing that fits well, use lubricants generously, stay hydrated, and consider wearing compression shorts or tights. By taking these steps and listening to your body, you can minimize friction, irritation, and potential blisters, allowing you to focus on your performance and achieve your marathon goals.
