What ever normal is for me. Ran 5 miles in the Mohican Class A campground area and even through in a couple of miles of muddy trail. Felt great. Was able to breath without the burning lungs. My vim and vigor was a little lacking as a ask my legs to move at 7 minute mile pace and they responded with a firm 10 minute pace. You take what the body allows. For now I am in a better frame of mind.
