By finishing fourth in that leading pack that sped in almost two minutes ahead of a chasing group that included the Tour's top four riders overall - Aru, Froome, French rider Romain Bardet and Colombian Rigoberto Uran - Landa clawed back valuable time in the overall standings.
Froome suffered a mechanical problem due to a broken spoke in his back wheel and found himself distanced as he had to stop and change a wheel with team-mate Michal Kwiatkowski. Thanks to my team-mates, Sergio Henao and Mikel Nieve, who helped me. "For a guy who's doing so well in the classics and capable of winning Liege-Bastogne-Liege and Lombardy, and Fleche Wallonne, which he hasn't yet (second in 2014 and 2017) but he will some day, I'm sure, to come here to the Tour and riding for GC, very few riders can say that", added Roche. "Kwaitkowski gave me his wheel because the team auto was far away". Riders don't race like they're going for the Tour win. It was a time of stress. I think the team managed pretty well. Contador has already lost 5:15 overall, but could still ruin the Team Sky masterplan with some relentless attacks on his favorite ground.
"We've always battled, we've been there and you don't lose quality overnight", said the Movistar team leader.
This caps a remarkable reboot for Federer, who departed Wimbledon a year ago with a lot of doubts: His body was letting him down for the first time in his career. I stayed calm and focused.
The main group of contenders marked each other over the rolling final kilometres, but Martin was allowed to pull clear with around eight kilometres left and claw back more time.
Dan Martin (Quick-Step Floors) was the biggest mover in the GC standings as Froome retained respective advantages of 18 and 23 seconds over Aru and Bardet.
The stage went through Carmaux, the hometown of Jean Jaures, one of the great figures of the French left and a committed anti-militarist who was assassinated in 1914 just after World War One broke out.
German Tony Martin tried a long-range attack, but after the Katusha-Alpecin man was caught on the Peyra Taillade, there were a series of attacks and counter-attacks.
Trek-Segafredo's Mollema attacked on the descent of the Peyra Taillade, and held off a chasing group of Warren Barguil, Primoz Roglic, Diego Ulissi, and Tony Gallopin over the final categorised climb, the Cote de Saint-Vidal.
"Crisis adverted? I think so, but I wouldn't say crisis". "I'm so happy to win a stage at the Tour de France".
"Chris had the same thing previous year when he had to run up Mont Ventoux and he got his time back". That was a big goal for me.
"I just gave it a try in the last 30km".
The Polish rider went all out, using his time trial skills to resist the peloton's pursuit as long as possible. It was close to the chases at the end.
Tour de France stage 15 will start at 6:25 AM ET and with the live television viewing in the United States by NBCSN which will begin the coverage at 8:00 AM ET.
