Britain’s Stephen Cummings crosses the finish line to win the seventh stage of the Tour de France cycling race over 162.5 kilometers (100.7 miles) with start in L'Isle-Jourdain and finish in Lac de Payolle, France, Friday, July 8, 2016.

LAC DE PAYOLLE, France — British rider Steve Cummings won the opening stage in the Pyrenees of the Tour de France with a solo attack on the well-known Col d'Aspin climb on Friday.

Greg Van Avermaet of Belgium held on to the yellow jersey he claimed two days earlier, while overall favorites Chris Froome and Nairo Quintana finished in the main pack.

Froome and Quintana were slowed when an inflatable arch marking the final kilometer was punctured and fell to the ground. They had to lift the arch off the ground and slip their bikes underneath it.

Thibaut Pinot, considered one of the top French contenders, was dropped on the Aspin.

Cummings, a teammate of Mark Cavendish on Team Dimension Data, also won a stage in last year's Tour.
