Primoz Roglic is taking nothing for granted, despite holding a comfortable lead in the Tour de France with four competitive stages left.
The Jumbo-Visma rider is in complete control of the race, after extending his overall lead to 57 seconds over fellow Slovenian Tadej Pogacar, with one mountain stage and a partly uphill time trial to come.
The 21-year-old Pogacar had been the most explosive rider, but in Wednesday's gruelling 17th mountain stage ending at top of the Col de la Loze, the UAE Team Emirates rider was on the back foot.
Colombian Miguel Angel Lopez prevailed 2304 metres above sea level, beating Roglic by 15 seconds and Pogacar by 30 to move up to third overall, 1m 26s off the pace.
"I don't think the job is done," Roglic says. "There are still some hard stages to come and Tadej Pogacar is a great climber.
"I felt really good on the climb, but you can't compare these last 4-5km to anything else. I'm glad this stage is behind us."
As the road rose up to 25% at times, Roglic still could count on teammate Sepp Kuss to attack and test his rivals' legs, while Pogacar and Lopez were on their own.
"Sepp Kuss and I talked during the climb, and we decided he could go and try to win the stage, as he could always drop back and help me," Roglic, 30, says.
"Also, the others tried to chase him back and it helped me realise many guys around me were struggling. Sepp's attack pointed me when to attack myself.
"On this climb, every metre counts. Having his help was really good.
"Again, it has been a very big performance from him and the team."
Pogacar and Lopez will have to take chances in Thursday's 18th stage to La Roche sur Foron, featuring the demanding ascent to the Plateau des Glieres, leaving Roglic in a comfortable position.
"The gap is never big enough," the Slovenian said. "You know, when you have something, you always want more, but I was happy with the position I was in before the stage and now I'm even happier."
Pogacar vowed to fight on.
"It's not finished yet," he says. "Tomorrow is a really hard stage and anything can happen.
"I can win, I can stay second - it's gonna be a great fight."
Roglic's teammate - Kiwi George Bennett - slipped a spot to 28th on the general classification, now 1h 38m behind the leader, with Jack Bauer in 87th.
