Interesting times. As I mentioned in another thread, I got some new Conti 4000's (not 4000s') for my Giant, making the switch from 28c to 25c... nice. I've been trying them everywhere to get a handle on the differences if any between my old and new tires. Of course, I've taken 'em up and -maybe more importantly- down my two favorite local climbs. They descend great and I've climbed the first mile of one of them 20 seconds faster than ever before. Don't know if that's all down to the tires, though, but they're keepers.
Unfortunately, another thing I've noticed is that I'm fighting harder and harder for air on some of these climbs. Legs feel OK, HR is within bounds... I just can't get enough oxygen in me. I've been going to the allergist for 13 years for immunization and my asthma and I was due for a re-eval. The results were disheartening. My main problem in the small airways and, at best -once, a couple of years ago- I got up to 80% on a PFT. That was after a case of sudden onset pneumonia that they were treating pretty aggressively. They had me on Advair 250/50 -a steroid inhaler- twice a day, later dropping me to 100/50. The last time, a year ago, I fell to 71%... this time: 54%. Well, that explains a lot. So, I'm back on 250/50 to see if it helps. I have some other theories to explain the drop and I expect a lot of improvement when I get retested in 4 months. But, if you want to know suffering in the hills, do them in immediate oxygen debt.
I'll just have to suffer and "stop & go" my way up the hills in the meantime but I have to wonder, if I can do what I'm doing with 54% capacity, how much better will I start to climb if I can get back up to 80%?
The allergist thinks she can do better than that, too. We'll see.
But the big moral is, you have no excuse.
Get out and do it.
If I don't let 54% lung capacity stop me, what's stopping you?
Still, how demorallizing...
I *do* love the tires, though
