When I did the AT I was a spry 26 & hiked a bit with Mountain Goat, Vern. My pace would leave him behind on the climbs yet catch up to me on the downhills. On my PCT hike I met & hiked with some with Brice Hammock then well into his 70's & slowed down by his 30ish daughter. When I met him at an ALDHA West conference a few years later I chatted with him about his summer adventures. He said his hike that year had really beat him up. No more long distance hikes for him! Nothing over 500 miles. I think he was 82 at the time. I hope I can hike like he did, doing the tripple crown twice after retired & then some.
I guess as I get older it's just slow & steady. Linger over views & flowers. I will lay out my sleeping pad & take an extended lunch break & read in pictures stops. Maybe read a little. When I did the high Sierra of PCT I bypassed in 95 I met up with Ranger Dave. When we parted company due to resupply one of the last things he did was thanking me for reminding him how to hike "Civilized". To me now the hike is the journy. Yes completing a hike means a lot, but no longer is my primary focus. I want to hike, enjoy my surroundings, meet people & experience the local area.
