Gilberto Simoni (Saunier Duval-Prodir) conquered the 10.1-kilometre Monte Zoncolan in 1850 metres per hour according to La Gazzetta dello Sport. The speed, 39 minutes over the 1203 metres, 1850 VAM (Velocity Ascended, Metres per hour Vm/h), was faster than that of Ivan Basso on the Maielletta Passo Lanciano in 2006, 1805 VAM. Marco Pantani blasted up the Alpe d'Huez with a 1791 VAM and Danilo Di Luca did the final four kilometres of Tre Cime di Lavaredo with a 1750 VAM.
Pretty interesting. I did 2000 VAM once while smoking a pack of American Spirits, it was cool.
