"Five time Tour de France winner Miguel Indurain is reported to have had a VO2 max of 88.0 at his peak [1], while cross-country skier Bjørn Dæhlie measured at an astounding 96 ml/kg/min.[5] To put this into perspective, thoroughbred horses have a VO2 max of around 180 ml/kg/min. Siberian dogs running in the Iditarod Trail Sled Dog Race sled race have VO2 values as high as 240 ml/kg/min.[6]" http://en.wikipedia.org/wiki/VO2_max#VO2_max_Levels
Does this mean that if I got my sister's Alaskan Husky to train for the Tour he would absolutely kick Contador's a$$ on Ventoux????? Just a "noob" that wants to know . . . .
Good stuff. Hilarious cartoon!

. Thanks for that. Some great laughs on these threads: there are a couple of wags around here.
Sled dogs are absolutely incredible. NB: Alpe d'Huez knows all about Daehlie, too.
To your question, you gotta believe it. Some animals have astounding VO2 maxes (think I had a post long time ago citing these figures). People don't realize that their pet poodle or [substitute whatever] sitting at their feet has far, far greater aerobic capacity than ANY procyclist will ever have--and that's without any training [one poodle, say= 1 1/2 Indurain's]. Dogs are born to run. Think just about all dogs are in the 100s. Even the lowliest draft horse or plowing horse can run better than Lance can cycle. So when anyone sees the winner of this year's Tour, look down at your lazy, snoozing, good for nothing pooch and think, "He could kick that guy's *** (relatively speaking), no problem".
The lesson for me: you can't put it what God/nature/genes left out. There are some iron limits. But, LOL, that's where the doping/blood manipulation comes in. The "fun and games" part, the shenanigans, where the streetsmart cons game the legal system, find the loopholes, etc.
And it's why the percentage of the VO2 max (the latter basically is an iron limit set from birth or establishd in teens) or threshold power, however defined, is the key training variable. Very painful one. But here is where all the blood chemistry business becomes so critical and where people like Ferrari, Conconi, Fuentes, and Cechinni are geniuses (where key differences can be made). It seems to affect not only power output of muscles, but the lactate production/clearing mechanism with the oxygen you do have (like high octane fuel, jet fuel, what have you). More bang for the buck/red blood cell carrying the oxygen burning the carbohydrate and fat, etc.
One other thing favouring a dog uphill (or a human runner on a really steep hill): cycling is very biomechanically inefficient going uphill. The energy transfer of the wheel is entirely straight back at the road's incline. A runner or dog (flexible legs/levers) can produce directed leverage, and push up AND backward simultaneously. Far more efficient on a hill.
So, yes, pooch will kick Bertie's (Contador's nickname) *** going uphill as long as it's steep enough.
P.S. Incidentally, Indurain has always been totally silent about EPO. Everyone knows why: EPO on his engine during the peak EPO era=five Tours. It's more complex now; more cat and mouse, or pooch and cat, LOL.
