A marathon is 26.2 miles, that is a long way to run. To run a marathon you need dedication, discipline and good nutrition and you can find the nutrition part at McDonalds! Imagine training for a grueling event with nothing but your Quarter Pounder and Big Mac to keep you company. You can do it! In my humble opinion McDonald's gets a lot guff from the media about their food. You can't blame McDonalds for an unhealthy lifestyle, if you eat and exercise you are going to be fine.
