link to the quote:buckle said:"Unusually for a track coach, Salzwedel is a believer in altitude camps and road races for his track riders, meaning he has had them schlepping up Mt Teide in Tenerife, most famously used by Team Sky for their Tour de France preparations, for much of the winter".
All this plus magic bikes and good hotels is all you need ...

On a side, Salzwedel's right hand at RusVelo, Russian-born Australian physiotherapist Popov (mainly known for working with McEwen), is a fan of altitude training, too.
Here he is making propaganda for 'altitude rooms'.

It's an interesting clip. Watch from 1:38, and then ask why Salzwedel is still sending his riders to Tenerife when those altitude rooms allow you to save "hundreds of thousands" of dollars (according to Popov).
I can think of plenty of additional gains from not sending your riders to Tenerife but sending them into an altitude room.
