Red cells, sleep and the two weeks after coming down, measured on twelve distance runners. What a month at altitude actually does.
The blood
Haemoglobin mass rose an average of 3.8% over four weeks — in nine of the twelve. The other three sleep badly at altitude and gained nothing except a month away from home.

The timing
The benefit peaks two weeks after coming down and is gone by the sixth. A camp that ends a month before the target race is a camp for nothing.
