Floyd in Morzine 2006 was big. I never thought that in 21st century a single rider could destroy the peleton with 100km+ breakaway like Merckx.
Santiago Perez at Vuelta 2004 was also spectacular. A man from nothing doing 1800-2000 m/h of VAM for 15 minutes and making Heras look like an amateur.
Jose Enrique Gutierrez at Giro 2006. A heavy man (78 kg) with no grand tour success is 2nd at the Giro ahead of Simoni and only behind ET Basso.
Pantani and Indurain on Alpe d'Huez 1995. Pantani goes under 37' and Indurain (80 kilograms!) doing a little over 38 minutes! Pantani doing well over 1800 m/h of VAM (close to 7 watts/kg) for such a long period is incredible. But what can you say about Indurain? This 80-kg giant with locomotive-like engine achieved VAM of about 1750 m/h and could overtake uphill our skinny Alien
What a mutant! Wonderful 90s. Compared to them todays cycling is clean
For me sustained greatness of Pantani and Indurain (for many years, not a single shot like Landis) represent peak of capabilities of very gifted cyclists on doping.
