2003 would be a breakthrough year for Vinokourov, but one marred by an early-season personal tragedy that nevertheless drove him to perform inspirationally.
His close friend Andrei Kivilev fell heavily during the second stage of Paris–Nice, slipped into a coma, and died during the night.
The loss of his compatriot weighed heavily on Vinokourov, but he rallied and declared that he was more motivated than ever to win.
Stage three had been neutralized and stage four was a time trial, but on stage five, which featured the race's only mountaintop finish, Vinokourov honoured his late-friend with a spectacular attack on Mont Faron that won him the stage and the leader's jersey.
As he crossed the line, Vinokourov pointed skyward, and later explained to the press:
Most of all, [it's a victory for] for Andrei Kivilev.
He wanted to win on Mont Faron and also Paris–Nice.
I really gave everything for this victory, and today was a coup double, for him and for his family.
I found the strength to continue the race, only for him, for his family, for his little boy.
I'm satisfied today for myself and for them.
I'm going to do everything to keep the jersey, and for that I found a double strength, myself and his strength as well.
It's fantastic, and I'm very happy.
