I learned something today. Namely, I learned that I am getting old.
I learned this on about mile 6 of a 10 mile hike, after about 2300 feet of elevation gain.
How did I learn this?
Well, I sat down with the rest of the group at the pinnacle of our hike. It was cold in the shade, and I was sweaty from the hike up, so I put on all my layers - long sleeves and midweight and raincoat.
When we all got up and started down the hill, I was still cold.
I took a few steps downhill, and my knee started hurting so badly that I thought I was going to need the Search and Rescue people to come up and carry me down on a stretcher.
The crazy thing is that it stopped hurting so badly when it warmed up. (Then it only hurt a little, as it always does on the downhills.)
I am an actual old person.
Which isn't going to stop me from doing 10 mile hikes, nope.
