1717 m/h was the VAM of the group of best riders led by Ivan Basso in the last 10 km of Alpe di Siusi (8.3% average gradient at an altitude of 1014 up to 1844m), a performance which is equal to 6.13 watt/kg.

A performance, that of Ivan, not so distant from his best ones in 2006: 6.27 w/kg on the Colle di S. Carlo (9.8% average gradient at an altitude between 1000 and 1900m), 6.39 w/kg on the Bondone (7.9% gradient, altitude between 278 and 1650m).

In the stage with the finish in Bergamo, on the Colle del Gallo (6.2 km at 7%, with an altitude between 328 and 763m) we have seen a small group formed by excellent riders such as Garzelli, Cunego, Pellizotti, Horner, Rogers, Leipheimer attack and literally devour the 435m of climbing in 14'11", with a resulting VAM = 1838 m/h, corresponding on such a gradient to an excellent 6.8 w/kg.

The group with the pink jersey Di Luca, Basso, Sastre, Menchov and a progressing Armstrong, got over the climb with a delay of 1', but still with the impressive VAM = 1720 m/h, equal to 6.35w/kg.
