Primož Roglič (Jumbo-Visma) dominated the Vuelta a España stage 10 time trial to take victory and the overall lead.
The Slovenian beat Nairo Quintana (Movistar) by over three minutes after finishing the 36.2km course in a time of 47-05 to take over the race lead.
Roglič beat Patrick Bevin (CCC Team) into second place on the stage, with all the other GC contenders failing to break into the top 10 on the stage.
Fellow Slovenian Tadej Pogačar (UAE Team Emirates) was the next best placed of the contenders, finishing at 1-29 down. The 20-year-old stays in fifth overall having won stage nine's summit finish on Sunday.
Alejandro Valverde (Movistar) and Miguel Ángel López (Astana) - who was caught by two-minute-man Roglič - both lost time, at 1-38 and 2-05 respectively. Valverde moves into second overall, while López takes third after Quintana tumbled down to fourth place.
How it happened
After the first rest day of the 2019 Vuelta a España, riders faced a test against the clock in a 36.2km individual time trial starting in Jurançon and ending in Pau, France.
While many riders would be simply happy to make it through the day unscathed and ready for the coming mountain stages, others would be eyeing time in the overall and the stage win.
The first potential winning time on the course came from Frenchman Rémi Cavagna (Deceuninck-Quick-Step), who set a blistering time of 47-22, putting over a minute into those that were on top of the stage standings.
His time looked to be seriously competitive, with proven time triallists Thomas De Gendt (Lotto-Soudal) and Nelson Oliveira (Movistar) unable to beat him. New Zealand national champion Patrick Bevin (CCC Team) was the rider who eventually took the hot seat from Cavagna, beating him by a mere two seconds.
Bevin may have fancied his chances at the stage victory save for one of the men left to take on the course. Primož Roglič, second overall at the start of the day and favourite for the stage, went quickest through all the checkpoints on the course and looked almost certain for victory before halfway through if he could maintain his pace.
What was certain is that the Slovenian would overturn the six second deficit to Nairo Quintana on GC, with the Colombian over a minute behind by the time he hit the first checkpoint at around 11km ridden.
Likewise Roglič was eating into the times of the Alejandro Valverde and Miguel Ángel López, eventually catching the latter - who started two minutes ahead of him - in the final kilometre.
In the end, Roglič won the stage by 25 seconds over Bevin, but more importantly now sits almost two minutes ahead of the next best rider on GC, Valverde.
López slips to 2-11 behind, while Quintana will have a mammoth task ahead of him if he's to win this Vuelta, sitting exactly three minutes behind in fourth place.
The 2019 Vuelta continues on Wednesday with stage 11, a hilly 180km stage in the Basque Country from Saint Palais to Urdax.
