I had the opportunity to travel to Colorado this summer. Having never been at high altitudes, I got my butt whooped pretty hard trying to bike in Pikes National Forest. My question is, when do you think you can start feeling the effects of altitude while exercising? I started out my ride at around 6,000 feet or so and could definetly feel the lack of oxygen effecting my work out from the get go. Would any mountains in the east give a person at least a little oxygen fatigue, say the 4,000 foot peaks in w. virginia, 5,000 in the smokeys? Just curious...I couldn't find any info on the net about altitude fatigue at more 'east of the mississippi' levels.

I don't know how to answer your question exactly, but personally, 4000 feet doesn't have any effect on me. Probably around 5000 is where I start to notice it, but it doesn't seem to affect my performance until I get much higher, around 9000 feet, which doesn't happen very often. Living at almost sea level, I don't have a lot of opportunities to get up that high. 4200 feet is the highest peak I can ride to from home.

and it depends for me. Usually though anything over 10,000 is noticable to me. Mt. Evans hillclimb ends at over 14,000 and you definately are sucking air at the top of that. It often makes me feel lightheaded and a bit dizzy. I suppose if you aren't used to 6,000 then you'd notice that too.
Kicks in at about 4000-5000 feet for mecory

I live at 5,000 feet now, outside of Reno, and I can feel the difference when I climb over about 7,000. When I lived in the Bay area, though, I didn't notice much until I reached 4,000 feet or so--Yosemite Valley was pretty much like home, but anything much higher took a toll. If you can find a place to ride at 4,000, I imagine you'd get some benefit.
Works the other way, too, of course. A friend who was a great climber here moved to Florida a few years ago, where the highest point is something like 340 feet above sea level. She kicked butt for awhile.

This is what alot of high altitude mountaineers can experiance if not porperly aclimatized. I know this is not the same but it is some good info on lack of O2 at altitude
