Nutrition Tips for Runners: Fueling Your Performance

Nutrition Tips for Runners: Fueling Your Performance

As athletes, runners know that proper nutrition is just as essential as training in achieving peak performance. Whether you’re preparing for a marathon, a 5k or just hitting the trails, how you fuel your body can impact your energy, endurance and recovery. At GHC-SCW, we recognize that nutrition is not only essential for maintaining a healthy lifestyle but also plays a crucial role in achieving optimal performance on race day. From pre-race meals to hydration and snacks, here’s what you need to know to fuel your runs effectively.

Pre-Race Meals: Setting Yourself Up for Success

What you eat before a race can make a significant difference in your performance. The goal of a pre-race meal is to top off glycogen stores, which are the primary energy source for endurance activities like running. However, you want to avoid foods that could cause discomfort, bloating or fatigue.

Timing is key:
Try to eat your pre-race meal about 2-3 hours before your race starts. This allows your body time to digest and absorb nutrients. For longer races, consider eating a slightly larger meal, while shorter races might benefit from a smaller portion.

What to eat:
Focus on carbohydrate-rich foods that are easy to digest, moderate in protein and low in fat and fiber. Carbohydrates provide the quick energy your muscles need during the run, while protein helps to stabilize blood sugar and repair muscle. Here are some examples:

  • Oatmeal with a banana – A simple and easy-to-digest meal that provides complex carbs.
  • Bagel with peanut butter or almond butter – The bagel gives you quick-digesting carbs, while the nut butter provides a small amount of healthy fats and protein.
  • Rice with lean chicken – For a savory option, this delivers complex carbs and lean protein.
  • Smoothie with yogurt, berries and spinach – A lighter option packed with carbs, protein and micronutrients to boost energy.

Hydration: The Foundation of Performance

Staying hydrated is crucial for any runner, but it’s especially important on race day when you will be exerting yourself for long periods. Dehydration can lead to fatigue, cramps and reduced performance. Here are some hydration guidelines to follow:

Pre-race hydration:
Start hydrating in the days before your race with 8-10 cups of water daily. On race morning, drink 8-16 ounces 1-2 hours before the start. Avoid consuming excessive amounts of liquid immediately before the race, as this can lead to discomfort.

During the race:
For races longer than an hour, electrolyte replacement becomes important. Water is great for hydration, but you’ll also need to replace electrolytes like sodium, potassium and magnesium to prevent cramping and maintain fluid balance. Many races provide sports drinks, but if you’re running solo, consider carrying an electrolyte-enhanced drink or electrolyte tablets.

Post-race:
After the race, continue hydrating with water or an electrolyte drink to replenish lost fluids. If your race was particularly long or intense, a recovery drink containing carbohydrates and protein can help support muscle repair and replenish glycogen stores.

Snacks: Quick and Effective Fueling

Snacking during training and on race day is an effective way to keep your energy levels stable. Depending on the length of your run, you may need to refuel mid-run or after the race.

Pre-training snacks:
If you’re heading out for a run and haven’t had time for a full meal, a small, easily digestible snack 30-60 minutes before can give you the energy boost you need. Some great pre-run snacks include:

  • Banana with peanut butter – A good balance of quick carbs and healthy fats.
  • Energy bar – Choose one with a balance of carbs, protein and fiber for sustained energy.
  • Half a granola bar or a slice of bread with honey – Low in fiber and easy to digest.

Mid-run snacks:
If you’re running for longer than 60-90 minutes, portable, easy-to-carry options are best. Try:

  • Gels or chews – Fast-digesting carbohydrate sources designed for endurance athletes.
  • Sports drinks – In addition to hydration, they provide quick energy and electrolytes.
  • Small pieces of fruit – If you’re running a race with aid stations, opt for fruits like oranges or bananas.

Post-run snacks:
Refueling after a run is crucial for muscle recovery. Ideally, consume a snack within 30 minutes of completing your run to support muscle repair and replenish glycogen stores. Good options include:

  • Chocolate milk – A balance of protein, carbs and electrolytes.
  • Greek yogurt with fruit – Packed with protein and carbohydrates to support recovery.
  • Trail mix – Nuts, dried fruits and seeds provides healthy fats, carbs and protein.
