My wife and I are just entering the GGG at 64 with retirement immanent, and plans for lots of hiking, backpacking, kayaking, etc. starting this summer.
Also, thanks to Jardine and BPL, much lighter packs, but I’m too cheap to get below 10 lbs and still be comfortable. Neoair helped a lot, as did a tarp instead of tent, lightweight trail shoes, and hiking poles mandatory for both of us all the time…they really helped with my sports-compromised knees and ankles.
Also plan to be the oldest on the trail some day, as well as oldest in my martial arts (TKD, Hapkido) classes. Come to think of it, I already am the oldest in those classes!
This summer starts our new life of adventure, we’ll see what compromises we end up making over the next few years. I expect we’ll keep the mileage to at most 15 miles per day (we rarely went farther, even when younger), depending on elevation gain/loss. Might carry a Spot, but no plans yet.
One minor problem is medications that cannot freeze or get too hot, I’ve kept them in a jacket pocket or in a pants pocket if it was cold, not clear what to do about heat.
