Cycling Performance: What is possible? 6.6 W/kg for 38 min on Alp d’Huez?

Is power output above above 6.2 W/kg indicative of doping? Bjarne Riis is estimated to have produced 6.8W/kg (480W) on Hautacam when he won the Tour in 1996. Armstrong’s estimated power output on Alp d’Huez was 6.6 W/kg (465W). Most trained cyclists would be able to produce a power output of 4 W/kg for 40 minutes. And we know that a decent cyclist will produce a VO2max of around 60 ml/kg/min. Ross Tucker looks at whether it is possible to ride with oxygen use at 81.96 ml/kg/min for almost 40 minutes.
