No matter how long they have been running, all runners need to make sure they stay hydrated and well-nourished. Food-wise, this is something that most people need to experiment with and find out what works for them. Ensure you are not eating too close to heading out of the door, as this could make for an uncomfortable run.
If you’re running on a hot day, it’s also worth adding some electrolyte tablets to your water to make up for what you have lost through sweat.
Make sure you eat a balanced diet and stay hydrated throughout the week, rather than just focusing on before and after your run.
