Foods to Avoid Before a Race: A Guide to Optimal Performance

November 13, 2024

Preparing for a race requires careful attention to training, rest, and—perhaps most importantly—nutrition. While what you eat is crucial, knowing what not to eat can be equally impactful on race day. Certain foods can hinder performance, upset your stomach, or lead to energy crashes, all of which can be disastrous for your hard-earned preparation. Here are some key foods to avoid before a race, ensuring you perform at your best when it matters most.

1. High-Fat Foods

Foods like fried snacks, heavy sauces, and creamy desserts are high in fat, which can slow down digestion and make you feel sluggish. Because fats take longer to digest, they can cause stomach discomfort or cramping during a race. Instead, stick to lean proteins and easily digestible carbs in the days leading up to your event.

2. Sugary Snacks and Sweets

While sugary snacks like candy bars, cookies, and sugary drinks can give you a quick energy boost, this is often followed by an energy crash. The spike in blood sugar can lead to insulin spikes, resulting in fatigue. Opt for complex carbohydrates that provide a sustained release of energy rather than quick sugar hits.

3. Dairy Products

Dairy items such as milk, cheese, and yogurt can be difficult for some people to digest, especially when nerves and excitement are at play. For those who are lactose intolerant or sensitive, dairy may lead to bloating, cramps, and even nausea. If you want protein, choose plant-based sources or lean meats instead.

4. High-Fiber Foods

While fiber is excellent for daily health, high-fiber foods like beans, lentils, and certain vegetables may cause digestive issues on race day. These foods can increase the risk of bloating and gas, which can become uncomfortable mid-race. Focus on lower-fiber carbs like white rice, bananas, or oatmeal for energy.

5. Carbonated Drinks

The carbonation in soda and sparkling water can cause gas and bloating, which is the last thing you want during a race. Stick to still water, natural fruit juices, or specially formulated sports drinks to stay hydrated without discomfort.

6. Spicy Foods

Spicy foods can cause heartburn or stomach issues, especially under the physical strain of a race. It's best to avoid any food with strong spices or seasonings in the 24 hours leading up to your race to keep your digestive system calm and steady.

7. Alcohol

Alcohol is dehydrating and can affect your sleep quality, which is crucial before a race. Even small amounts of alcohol can impair hydration levels and hinder your body’s ability to recover from training. It’s best to avoid alcohol in the days leading up to your race to ensure optimal hydration and focus.
