Back in the early 2000s you pretty much had a new monster challenging Heras during the Vuelta every year.
Yeah lmao, I have been rewatching a ton of Vueltas lately. Who's the most blatant out of Santí Perez, Aitor Gonzales, Angel Casero, Oscar Sevilla and Isidro Nozal? Nozal was actually really good in 2004 as well, go look at the climb up to Aitana, lmao. Big ring just smoking Mancebo, Valverde and Sastre of the back at 7% and then attacking later to finish a couple of seconds behind mythical Heras who he had pulled for whole climb, lol. Seriously, go watch the climb, ridicolous scenes from big Nozal. That reminds me of another spanish rider, this time a guy I literally had never heard about before: Jorge Ferrio. Had to look him up, and he doesn't really qualify I think, but he climbed wonderfully in that particular race.
Anyways, I'll nominate both Santí Perez and Isidro Nozal. Especially Santí, Roberto Heras could not believe what he was just witnessing in that 2nd part of the race. Everybody thought it would be Valverde and maybe Mancebo challenging him, and then at some point Santi just began to smash it every time the road went uphill from the midpoint of the race. That ITT up to Sierra Nevada was a thing of beauty, and so was his win over Monachil.
