Nutrition is a key part of the preparation and recovery of a sports event.
Whether you’re having a crack at a fun run, or maybe even your first full marathon, physical training programs alone can only get you so far. For the best shot at success, make sure you have your nutrition-thinking cap on before, during and after your training so you can perform and recover.

Exercise can put your body under some strain. This triggers your body to adapt and grow to take on future challenges. Nutrition plays a huge role in driving your ability to perform better during exercise, and helps you refuel, repair and rehydrate during recovery.
When you’re exercising, your body draws on its reserves of glucose, stored in your liver and muscles as glycogen. To refuel, you need to replace your glycogen stores, particularly in the first hour after exercising. Carbohydrates are an important food source to replace your glycogen.
