Here's a decent breakdown of expected losses:


Joe Friel - Altitude and Aerobic Performance
It is well known for someone that lives at lower altitude it drops as they go up. What about those that live high?
I believe that is the chart I was talking about. 14,000 ft data on racing cyclists is hard to get I expect, but the chart has it.

I saw junior have his highest 5 min power at 7,000 ft. He has not duplicated it at sea level. Lately he has a (new) PM 50% of the time he rides. So I thought if the reciprocal were true (it should be right?) then he'd do more power at sea level. He didn't. He's about the same power at both.

I looked more and had to sign up for an academic subscription (Academia.edu) to find the source. I recall it uses actual records up to about 7,000 then extended/calculated after that.

Anyway - there are not enough real data points from other racing cyclist at 14,000' to convince me of anything.
