You're going to need to eat a lot of healthy carbohydrates in order to train for and complete a marathon. Around 65% of your daily calories should be in this area. Another 10% of your daily diet should be filled with protien such as lean meats or beans. Around 25% should be unsaturated fats because of all that you are burning up during those runs.

Hydration

Drinking plenty of water is crucial. Always drink the recommended 8oz a day. When going on runs that take more than one hour carry water with you and try to drink about 6oz every 20 minutes.
