Diet plan overview

A marathon training regime requires not just dedication and hard workouts but also a diet that supports extended physical exertion—and here comes in the allergen-free diet plan for marathon training. Full of carbohydrates that come from sources which don't trigger allergies, such as rice and quinoa, it also includes ample protein for muscle recovery and fats for energy hits that last. Great attention is paid to hydrating foods and those rich in electrolytes to forestall cramping during a long run.

The diet also decreases inflammation with omega-3-rich foods like flaxseeds and chia seeds, which are important for recovery and endurance. Runners can easily adapt this diet to their training schedules by making sure they have the right fuel at the right time of activity.

How to budget on this diet plan

Go for sweet potatoes and oats, two very cheap carbohydrate sources that are chocked full of energy and will not be allergenic. Make peace with bulk bins and stock up on quinoa and rice, which are primary go-tos for many dishes based around carb sources. Skip the fancy sports drinks: Water is best; you can make your own electrolyte drink with the juice of some lemon, salt, and sugar. Meal plan each week and cook large batches to save time and money. Frozen fruit is usually on sale regularly and can also be a great post-run recovery treat.
