It was only a few years ago could bust a 30 mile day if I wanted that challenge, but not lately…. Last summer I could feel a real energy drain on my section just north of the Smokies. I except that I’m not the hard charger I was a few years ago but am still in good shape and looking forward to many more years of sectioning the trail. Looking for advice on boosting that energy…Supplements? Diet? What’s worked for our “mature” hikers?
