Nutrition tips for marathon runners

RUNNING THE MARATHON? 

Here are some vital nutrition tips:

1.   STAY HYDRATED

It’s really important to be hydrated for the marathon. The trick is in the preparation. You don’t want to be making lots of toilet trips during the race! Drink plenty the week before and in the morning 700ml will do, avoiding any for the hour before the race.

Make sure you have water throughout the run, but don’t feel the need to drink constantly. The most recent research suggests it’s best to drink when you are thirsty. This helps avoid over-hydrating and can also reduce gut discomfort and improve performance on the day. Coconut water is also a great natural alternative to the energy drinks in replacing lost hydration, sugars and electrolytes during the race.

2.    FAT THEN CARB LOADING GIVES MORE ENERGY

Research has shown that a diet (short term) high in fat before you embark on the more traditional pre-race carb loading offers great benefits for increased energy. 10 days of fat loading are enough to increase the muscles fat burning capacity, while the three day carbohydrate load ensures muscles have plenty of glycogen available for energy.

In the fat loading days, start 2 weeks before the race and aim for 65% of your total calorie intake from foods containing healthy fats. These could be avocados, cheese, eggs, salmon, whole milk, Greek yoghurt, nuts, olives and olive oil. In the carb loading days, start 3 days before your race and aim to get 70% of your total calories from carbohydrates.

3.    DRINK BEETROOT JUICE

Beetroot juice is packed with dietary nitrates, which dilate blood vessels, increasing blood flow to muscles during exercise. Studies have shown that drinking 500ml of beetroot juice 2-3 hours before running can enhance performance. Try it on a couple of training runs before your marathon day and see if the red juice helps.

REMEMBER YOUR NUTRITION IS FUEL
Getting it right can really make the difference not only in performance, but your enjoyment of the day. Good luck and fuel smart.
