With every type of sport, there are different diets to help you perform to your best of ability. For runners, diet is very important to your performance, whether you are running for time or endurance (longevity). Your before/after training and pre/post racing meals are essential to keeping you not only on track with your running goals, but injury free during them as well. I just recently started a book called Run your Butt Off. It reminded me of way back when I used to race in 2007 of how strict I was on my dieting..and also remembering all the pluses to a runners diet that you usually won't find in a regular, weightloss, building muscle mass or even a cutting diet. So take advantage of this, learn what to eat and when. Below is a list of foods that should always be on a runners diet as well as some examples of pre/post race day and training diets.
Runner's Food List:
Proteins/Dairy - Although runners do need protein, they don't need to have excessive amounts.. eating 15% of you daily diet of proteins works well.
