Chris Froome has virtually sealed a fourth Tour de France victory on the penultimate stage, stamping his authority on the race in a time trial in Marseille streets.
Froome, the last rider to set off from the Stade Velodrome, finished third in the 22.5-kilometer stage won by Maciej Bodnar and increased his overall lead.
Colombian rider Rigoberto Uran moved to second place in the general classification, 54 seconds behind Froome, after Frenchman Romain Bardet cracked and fell to third overall, according to provisional results.
Only the largely ceremonial stage into Paris on the Champs-Elysees stands between Froome and his fourth triumph in five years.
The British rider from Team Sky also won cycling's biggest race in 2013, 2015 and 2016
