The French rider Pierrick Fedrigo has given the hosts their fourth win of the Tour de France after pipping the American Christian Van de Velde on the 15th stage.
The overall leader Bradley Wiggins and the main peloton finished nearly 12 minutes behind a five-man breakaway, and the Briton was under no threat during the stage to Pau at the foot of the Pyrenees, where they'll spend their second rest day.
Greg Henderson was 92nd on the latest stage, the New Zealand veteran is 120th overall on his first Tour de France.
Two more mountain stages and an individual time trial remain for anyone to challenge Wiggins as he bids for his maiden Tour title.
Wiggins has a two minute and five seconds lead over his team-mate Chris Froome, with the Italian Vincenzo Nibali third and Australian defending champion Cadel Evans fourth.
