Nutritional Advice for Runners
Nutritional advice for runners.
Running is one of the most popular sports worldwide. Whether you are just starting out or have been training for years, running offers numerous physical and mental benefits. It improves your endurance, strengthens muscles, helps with weight management and can reduce stress. But to get the most out of your running sessions, proper nutrition is just as important as the workout itself.
Nutritional requirements for runners
As a runner, your body has specific nutritional needs. Whether you are training for a 5K or a marathon, the right balance of carbohydrates, proteins and fats is crucial to provide energy, recover properly and prevent injury.
Carbohydrates as a source of energy: Carbohydrates are the most important fuel for runners. Choose mix of carbohydrates such as pasta, quinoa, rice or sports foods that will give you energy for both short and long distances.
Protein for recovery: After an intense workout, your muscles need protein to recover and become stronger. Proteins are the building blocks of your body so if you want to recover better and get stronger as a runner then proteins are essential.
Hydration: While running, you lose a lot of fluids and electrolytes. It is important to drink enough both during and after your workout. An isotonic sports drink can help restore your fluid and mineral levels. An isotonic sports drink contains carbohydrates and minerals and is therefore better absorbed than water alone.
10 km nutritional advice
10 km - 40-50 minutes
Before the start, take 1 Energy Shot and 1 Magnesium Shot. Halfway through the race take 1 Pro Fruit Gel. Also test this schedule during your workouts.
10 km - 60-70 minutes
Before the start, take 1 Energy Shot and 1 Magnesium Shot. After 25 minutes take 1 Pro Fruit Gel and at 45 minutes take a second gel. Be sure to try this schedule in your workouts as well.
Use 1 Pro Fruit Gel every 20 minutes or 1 40-carb Fruit Gel every 30 minutes. Halfway through take a Magnesium Shot and 1.5 hours before the finish line take an Energy Shot. Make sure you also drink enough, both on the road and after the race. Also test this schedule during long workouts.
