The 11 Best Protein Sources for Runners

Protein is important for runners, and some sources are better than others.

Protein is a very important component of a runner’s diet. Your muscles are, after all, made of protein. And the protein you include in your marathon training diet or triathlete diet needs to be adequate to promote fast muscle recovery after workouts and to ensure that your muscles adapt fully in response to your training.

That said, some dietary protein sources are better than others. The best protein sources are those that offer a balanced profile of amino acids (the “building blocks” of proteins), the highest concentrations of protein, lots of other essential nutrients, and healthy fat profiles. Here are our top 11 recommended protein sources for runners.
