Chris Froome believes winning a fourth Tour de France title will be the biggest challenge of his career.

Speaking at Team Sky’s pre-race press conference the three-time Tour de France winner said this year’s course could lead to an ‘open race’ and highlighted the form of his key rivals.
Froome said: “This is definitely going to be the biggest challenge of my career to date. The level of my rivals and the course we’re racing on this year means it could be a very open race.
“With less mountain top finishes and less time trial kilometres it leaves less opportunities for GC contenders.

“To win a fourth Tour de France title would be incredible.”

Asked if it would be the biggest victory of his career, Froome continued: “It would be right up there. To win a fourth Tour de France title would be incredible. I don’t want to jinx it, but it would be unreal.”

Froome also revealed that he expects to sign a three-year contract extension in the next few days, keeping him at Team Sky until the end of 2021.

He said: “Hopefully by the time we start on Saturday the t’s will be crossed and i’s dotted. We’re in the final process now of agreeing an extension.
“I think I’ll probably, at best, have five or six years left at the top level and I’d like to be here at the start of the Tour de France aiming to win the race. I came into the sport quite late and I feel as if I’m still quite young in cycling terms. I’ve got a bit of catching up to do.”
Looking ahead to the opening week, Froome believes that the stage five summit finish up to Planche de Belles Filles – the scene of his first Tour de France stage win – could create some early gaps between the race’s contenders.
He added: “I don’t expect it to make a big difference but I expect there will definitely be differences between the GC guys.
“It’s not important to prove anything but of course it’s the first opportunity to really take the race on and see where everyone is at.
“Tactically it’s going to be an interesting race and the strength of my team is really going to help me over the next few weeks.”
