German Lennard Kamna produced a superb solo break to power to victory on stage 16 of the Tour de France as Primoz Roglic maintained the overall lead.
The Bora-Hansgrohe rider, 24, pulled away on the penultimate climb of the 164km stage from La Tour-du-Pin to Villard-de-Lans to claim his first career Grand Tour win.
Roglic finished almost 17 minutes later in a group of the main contenders.
He leads fellow Slovenian Tadej Pogacar by 40 seconds.
Kamna, whose victory also marked his team’s first success at the Tour, finished one minute and 27 seconds ahead of Ecuador’s Richard Carapaz in second, while Swiss Sebastien Reichenbach took third place.
“I’m feeling great,” said Kamna who finished second to Colombia’s Daniel Martinez on stage 13.
“It’s an absolutely awesome day for me now.
“It was a fight from the beginning on and I knew I had to make it to the finish alone. When I saw Carapaz upping the speed I thought, ‘now is the moment to go’ – and I just went all in to the end.
“It’s a big, big, big relief for the team and for me. I can almost not imagine it. The step I made this year is huge and I’m so pleased to win.”
It was another disappointing day for defending champion Egan Bernal, who cracked on the Grand Colombier in Sunday’s 15th stage.
The Ineos Grenadiers rider finished alongside the sprinters more than 27 minutes down on Kamna and around 10 minutes inside the time limit.
Earlier on Tuesday, all 22 teams were cleared to start the stage after the entire ‘race bubble’ of 785 riders, team staff and officials came out negative for coronavirus in the latest round of testing.
French health authorities and organisers Amaury Sport Organisation (ASO) had said that if two members of a team, riders or staff, tested positive for coronavirus, the whole team would be excluded from the race.
Backroom staff from Ineos Grenadiers, Mitchelton-Scott, Cofidis and AG2R-La Mondiale, as well as race director Christian Prudhomme, had tested positive prior to stage 10.
On Wednesday, the Tour takes in a brutal 170km mountain route from Grenoble to Meribel Col de la Loze, in a day that is likely to ignite the general classification race.
