WHY IS NUTRITION IMPORTANT?

ENERGY
FUEL UP ON CARBOHYDRATES

Carbohydrate represents the main fuel source during a half marathon. When consumed, carbohydrates are broken down into glucose, which is then stored as glycogen. During the race, glycogen can be quickly converted to energy, supporting sustained effort. Consuming carbohydrate during the race also improves performance by providing an additional energy source.

HYDRATION
REPLACE KEY ELECTROLYTES

Hydration plays a key role in supporting performance during a half marathon by maintaining fluid balance, regulating body temperature and supporting muscle function. As you sweat during the race, you lose both water and key electrolytes, which can negatively impact your performance. Consuming sufficient fluid and electrolytes before and during the race is key for keeping you hydrated and helping you maximise your performance.

RECOVERY
PROTEIN AND CARBOHYDRATE TO AID RECOVERY

Optimal recovery after a half marathon is crucial for repairing your body, restoring your energy stores and allowing you to get back to running. Consuming protein and carbohydrate soon after the race is essential for repairing your muscle and restoring your glycogen stores. To rehydrate effectively after the race, you should focus on your fluid and electrolyte intake.

FUELLING RACE DAY

Consuming additional carbohydrate prior and during the race improves your performance by maintaining your blood glucose levels high, delaying the use of your glycogen stores and reducing the sensation of fatigue. ​

This guide sets out some simple steps for carbohydrate loading, pre-race meal and in-race fuelling to help you reach your own podium. ​
