When I was young and strong, I rode my fully loaded touring bicycle from
Denver, up through Bolder, and then over the pass in Rocky Mountain National
Park (12,183 feet above Sea Level). IIRC, it took me 1.5 days to reach the
top of the pass, so I got acclimated to the thinner air. The cars, however,
were coughing and choking and dying.
Riding down was a different story. After riding around between 9000 and 10000
feet for a week, I descended into Colorado Springs, dropping over 3000 feet
in 3 hours. The thick low altitude air felt like syrup in my lungs -- I
thought I was drowning. The next day it seemed normal :-)
That was when I was young and strong. Today, riding over a freeway overpass at
sea level here in Florida is plenty of challenge for me :-)
