Britain's Chris Froome, the current leader in the Tour de France, said Tuesday that he views Spaniard Alejandro Valverde as the main threat to his hopes of winning the three-week-long race.
Valverde, who rides for Movistar, trails Team Sky's Broome by 1 minute, 25 seconds in the General Classification after 10 stages.
Another Spanish rider, two-time Tour champion Alberto Contador, sits in sixth place, 1:51 behind Froome, who finished second to countryman Bradley Wiggins in last year's race.
Marcel Kittel, a German on the Argos-Shimano team, won Tuesday's 10th stage in a sprint, edging out compatriot Andre Greipel and Briton Mark Cavendish.
The 11th stage is a 33-kilometer (20.5-mile) individual time trial from Avranches to Mont-Saint-Michel.
Froome is a better time-trialist than any of his principal rivals in this year's Tour.
"Tomorrow's definitely a day where I will try to extend my lead," Froome said. "I do look forward to it. It's definitely a day that could help the General Classification. I definitely want to go for it." EFE
