I would like to be empathetic of your view but it doesn't work for me. Grumpy is not the term I would use. You do your thing and let them do theirs. This is not an age related view point. None of us have a clue as to why others do what they do. I am my own competitor and am happy with that. I push myself most of the time but there are times when I don't' want to ride but do anyway and just take it easy.
Do I ever walk a bike up a hill? I have, but it was when I was still in poor condition. I got over it by riding more. Did it bother me that I had to walk it? Yes because walking in road shoes with cleats is really tough. I started using a MTB to get into shape so I wouldn't have to walk it. But that was a personal decision. I didn't do it because someone on a SS passed me going up a hill.
A lot of 20 40 year olds hardly ever ride a bike. Nice weekend rides are not the same when you do them every couple of months or even weeks. If you commute and then have a weekend ride, your in much better shape.
This is me being grumpy!
