Fuel for RUNNING

I am very new to the running scene, but I have taken many nutrition classes and got my degree in Culinary so I think maybe that is why I haven’t had experiences of cramping or feeling sick while running or feeling sore afterward. Granted I’ve never ran further than 3.7 miles, but I can run that far very consistently with no sore muscles or really anything to complain about. I have always had a higher carb day the day before I run and drink a Gatorade right after I run and after about 15 minutes of stretching I drink a protein shake. It really seems to get the muscles back.
