Energy bars are another good choice for before or during a distance run. They are portable, resemble real food and can provide you with much needed nutrition and energy if chosen wisely, an alternative to other energy sources such as gels.
Distance runners should choose a bar containing at least 40gs of carbohydrates and avoid bars high in protein which are more beneficial to help repair and build muscles after training, particularly strength training. Energy bars for runners are more about fuelling and replacing depleted carbohydrates therefore reducing and controlling fatigue.
Bars containing natural ingredients such as dried fruit, soluble fibre and whole grains are a good choice. Many bars can also provide additional benefits such as vitamins and caffeine which can boost performance.
