After a three year hiatus due to working full time while going to grad school, my wife is able to join me on backpacking trips again.
She, quite frankly, has lost her trail legs. See above.
What I do know is that carrying a sub-10 lb BPW pack (I carry a little more at 15lbs or so on these trips) has allowed her to enjoy our very moderate 5-10 MPD.
Perhaps if she did these shorter mile days with 35 lbs BPW the hike would magically be more enjoyable? I sincerely doubt it.
A ULA pack that fits her well, a good down bag from GoLite and a NeoAir certainly makes her comfortable vs the older, more traditional gear she used to use that was heavier.
Going light does not mean going far or fast.
Now does going light does not mean sacrificing comfort. IF anything, it has enhanced comfort in my wife's case.
And going far does not mean not enjoyable. Strolling along at 2.5 MPH for ten hours can be very rewarding.
Overall, the article was click-bait. And, yeah, we all fell for it (myself included) :)
Now, if you'll excuse me, Mrs Mags and I are off to do a foothill stroll very shortly. We'll probably go 1.5 MPH. I doubt we'll do more than 3 or 4 miles. I suspect I'll enjoy that, too.
