Camps on how to climb are stupid and a waste of money. There is no technique that can teach brute strength. Hence the doping for guys like Rasmussen.
What else could he recommend to an audience of middle-aged, bloated North American yuppies? Going on a POW diet of 150 calories a day for 3 months?
*****Those middle-aged bloated North American yuppies help to pay the bills! More serious racers including an overwhelming number of professionals in the US don't have two nickels two rub together, and some of them supplement their income by doing these camps. Triathlon camps are much the same, and it's good money.
I remember reading that Carmichael had lots of training camps during the Lance years, at several thousand $$$ a pop for him to personally run them, and climbing techniques were amongst the first order of the day after a big breakfast! There were usually some guest speakers - current and former professionals, etc... that shared their secrets to paying members of this camp.. This was info you would never see in fitness columns in Bicycling magazine - this was the really good stuff...
Sure, it was expensive, but... You got a really nice team clothing kit, water bottles, and a bunch of supplements/gels/bars, etc... along with specific techniques to improve Max VO2, threshold power, sprinting capability, and other important techniques just like Lance learned from Chris Carmichael himself. Need I mention that Chris personally coached Lance to 7 Tour victories???
Imagine having a coach like that guiding you to reach your potential as a cyclist ! Perhaps you are too heavy to battle for an overall Tour victory (I mean, look at Jan Ullrich... all of those 2nd place finishes at the Tour.. If ONLY he spoke English and could have attended a CTS camp...), but you can still improve other facets of your cycling, and maybe win a lesser race like Milan-San Remo, or Paris Roubaix, etc...
