Performances at the TdF 2009

19 Jul 2009

On the ascent to Verbier (638m of difference in height at 7.5%) Alberto Contador (62kg) climbed at 1852 m/h, equal to 6.73 w/kg, developing an average of 417w.

Lance Armstrong (72 kg) climbed at 1720 m/h, equal to 6.25 w/kg, developing 450w.

The difference between their VAM's is 7.4% in favor of Alberto, while Lance, whose body weight is 16% heavier, pushed 8% more watts: a suggestion that in the upcoming time trial in Annecy it could be a very close and uncertain duel.

In Arcalis (751m of ascent at 7.1%) Contador climbed at 1671 m/h, equal to 6.18 w/kg, with Armstrong and all the other best riders at 1649 m/h (6.10 w/kg); but in the last couple of km Alberto had already showed a power that was 7.2% superior to his rivals'.
