My hat's off to you.There have been people forced to move out of Reno because of endless altitude illness. But that makes me wonder about Denver which is at over 5,000 feet and is known at the mile high city.
In my only experience riding out from Reno, on an otherwise
moderate climb, I stopped to throw up. Altitude sucks.

I'm surprised about this; my impression was that up to around 5,000 or >>6,000 feet, most people might suffer a day or two but everybody adjusts >>easily.
I have heared of people being unable to live at 10,000 feet and more >>(e.g. Lima, Peru).
"Effects of high altitude on humans" ><https://en.wikipedia.org/wiki/Effects_of_high_altitude_on_humans#Athletic_performance>
"For an unacclimated individual, VO2max begins to decrease
significantly at moderate elevation, starting at 1,500 metres (5,000
ft) and dropping 8 to 11 percent for every additional 1000 metres
(3,300 ft)."
Interesting. In the fall of 2025, I cycled up and down Mont
Ventoux, from 700 meters to 1,900 meters. <https://brouter.m11n.de/?lng=3den#map=3d12/44.1323/5.3759/standard&lonlats=3d5.412527,44.096559;5.278869,44.173617;5.40912,44.092297&profile=3dfastbike>

Should I have noticed an effect like that, at my age? Of course,
it was somewhat exhausting. But not any more than I would have
expected.

I went up the upper part more slowly because it simply is
steeper. For the most part, I maintained a constant power, but I
slowed down a bit in the final kilometers because the slope got
steeper there and as expected, I was feeling a bit exhausted.
That didn't stop me, however, from riding up the last, even
steeper ramp to the observatory at a faster pace.
I have to watch my heart rate now since I don't want another stroke. But when I was in my 70's I had very little trouble with a 20 mile climb of 7%. Also the ride out to and back from Moraga had several 12% sections that I would climb at 12 mph. The distance between my resting heart rate and max heart rate is too narrow for that now.If altitude didn't make a difference why do ppros train in Peru or to get used to altitude by gemneratomg mpre red blood cells? This does NOT correct for the lack of oxygen but it does decrease the effects of it.
Who said that altitude doesn't make a difference? I've got the
first hand impression that <1900 meters doesn't make much of a
difference for a single ride, four watts, maybe. That's something
different. It can be measured through repeated experiments under
controlled conditions, but it is not noticeable under
uncontrolled conditions if you are healthy and know and respect
you limits.
I didn't do that ride to win a competition where every second
counts.
