3. Get the right fuel in your tank
It sounds obvious to say, but training and running a marathon is a whole different ball game to trotting out a 10k. You can't underestimate that. It means looking at what you eat to fuel your training, help you recover and actually power you on race day.
A lot of people take up running to lose weight and see marathon training as the perfect motivation to drop a few pounds. However, it's vital that you're getting the right fuel for your training.
Myfitnesspal is a fantastic app that lets you track your daily intake, with detailed information on the main nutrient groups so you can ensure you're getting enough carbs, vitamins and all the vital fats. You can connect it with running apps like Endomondo to help make sure your calorie intake is at the right level, while the barcode scanner makes it a doddle to record almost any food.
