Eight to ten hours nightly, sustained for four to six weeks, accumulated to roughly 300 hours of total exposure at 2,500m (8,202ft). That is the dose. Below it, the haematological response is partial. Above it, the response plateaus. The rest of this article shows where each of those numbers comes from. The...

Athletes who run altitude blocks face two practical questions about persistence. When does the peak performance window land after redescent? How long do the gains last before declining back to baseline?

Altitude training was simply part of the calendar, the same way intervals or recovery rides were. The protocol was not a trend then, and it is not...

The question sits at the centre of every serious altitude buyer's decision. Is simulated altitude as good as real altitude?

Some marginal physiological differences exist around...
