Yeah, biking 20 miles doesn't seem like much to a lot of riders. Last year, towards the end of summer, I could do 30, but that was only after working up to it starting in April, and biking about every other day.
This year, I haven't ridden much at all. 14 miles was about my limit. Today, I was pretty well pooped after 17, but I also should have taken more water. I'm sure I could not have done this had I been smoking for the past 3 months. (Well, I probably could have pushed on through, but I'd've been a wreck afterwards.)

It must have been glorious! Was it a beautiful ride?

Maybe your memory of how it felt in the past has made you build it up in your mind to being more dramatic than it actually is, so maybe you are feeling better, but not as better as you remember, giving you the impression that you're not any better at all. Or... Maybe now that you're older than you were the last time, the feeling is taking longer to take hold. Or... Maybe you're coming down with something. Or... Maybe something else is acting as an irritant to your lungs (like formaldehyde or something else in the environment). Or... I'm out.
