Marathon Prep Meal Ideas

As a nutritionist, I know that what you eat in the days leading up to a marathon can make a significant impact on your performance. Your meals should be rich in complex carbohydrates for sustained energy, high-quality protein for muscle repair, and healthy fats for endurance. And if you’re prepping for the London Marathon, you’ll want easy, quick-cooking meals to save time and keep you fuelled.

Two kitchen appliances that can make this process effortless are the air fryer and the Instant Pot. Below, I’ve outlined three marathon-friendly meals that can be cooked in each, giving you delicious and nutritious options to power you through training.
