And let's be really sharp about this Tenerife drivel.
Altitude training means Live High, Train Low. It's complete nonsense to think that riding up that mountain is a good idea (muscle damage ahoy). Live High, Train Low can be mimicked much more effectively by using an altitude tent.
If anything the Tenerife trainings camp seem rather old-fashioned. It's one of those touted marginal gains that are very dubious upon closer inspection.
Why go to Tenerife if it's an expensive, inefficient way of training? Why do people like Wiggins and Vinokourov swear by this training method?
I cannot be certain of this but my general feeling is that pretty much every pro-cyclist these days would own their own altitude tent. They cost about as much as an intermediate sprint bonus.
A PhD student at the AIS did a study a few years ago where they examined LHTL, LLTH, LHTL + TH, and control. The LHTL + TH added 3 or maybe 5 sessions per week x 60min in hypoxia.
The best performance and VO2max responses came from the LHTH group with the LHTL coming in a close second.

I think that travelling to a location with a bunch of altitude tents and where you can access natural altitude is a great strategy. Randy Wilbur has also done studies which show that if you live at altitude but then use supplemental oxygen for high intensity training, you get pretty good outcomes also.
