So how far do you run? I run between 5 or 6 miles every other day and then on a weekend I might run 12 -14 miles. How do you refuel your body and muscles? My body cramps up if I don't refuel it with protein after a run. This sounds very interesting I am just not sure it would be good for a person who burns up as many calories as a runner does; as they do not have a lot of (if any)fat reserves and then you would start burning muscle.
