Make sure you're giving your body all it needs in the week leading up to an endurance event. Sports nutritionist, James Collins explains why by Wednesday your carbohydrate intake should be on the rise...
Overall dietary guidelines:
Runners should try to get into the habit of eating 5-6 smaller meals earlier in the week before a marathon, to train the body for the 'carb-loading' over the 2-3 days pre-race. Evening snacks are optional earlier in the week. Runners should look to use fluids and light snacks if finding it difficult to tolerate the increased quantities of food.
Jog for 70 minutes
* Beginner's guidelines as recommended by the London Marathon.
Carbohydrate intake is raised today at the main meals. A low Glycaemic Index (GI) breakfast provides a slow energy release during the morning to fuel the longer run. Now that training volume starts to increase, your diet should be high in antioxidants (morning and evening snacks) and protein in the evening - both will help to support ongoing muscle repair as the race draws nearer.
