Germany's Lennard Kamna won stage 16 of the Tour de France from a breakaway in Villard-de-Lans.
Kamna accelerated away from Richard Carapaz at the top of the penultimate climb of the 164km stage from La Tour-du-Pin to take his first career Grand Tour win.
After seeing Egan Bernal slip out of overall contention on Sunday, the Ineos Grenadiers were prominent in a 23-strong breakaway group, with Pavel Sivakov and Andrey Amador joining Carapaz in going up the road.
Nicolas Roche, whose father Stephen took the yellow jersey in Villard-de-Lans back in 1987, was also in the breakaway, which splintered on the climb of the Montee de Saint-Nizier-du-Moucherotte a little over 20km from the line.
Carapaz put in an explosive attack but Kamna was able to follow and proved the superior rider on the valley road to distance the Ecuadorian, who rolled in second a little over a minute later.
The 24-year-old Kamna said: "I'm feeling great. 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 today."
The main group of contenders, happy to let a 23-strong breakaway have their fun up ahead, came across the line almost 17 minutes later with race leader Primoz Roglic and Tadej Pogacar locked together to maintain the 40-second gap between them, as Miguel Angel Lopez looked to steal a few seconds ahead.
Last year's winner Bernal, having dropped out of contention when he was distanced on the Grand Colombier on Sunday, was again off the pace and rode home in the grupetto alongside the sprinters and other stragglers down the mountain – at least managing to smile and joke as he did so.
