Decathlon CMA CGM Team's Dutch rider Olav Kooij celebrates after winning the fifth stage of the 113th edition of the Tour de France cycling race, 158 km between Lannemezan and Pau in southwestern France on Wednesday.

Dutch debutant Olav Kooij won the fifth stage of the Tour de France in a chaotic sprint finish after a crash just over five kilometres from the line.

The 24-year-old beat German Max Kanter into second with Belgian Tim Merlier coming home in third as Norway's Torstein Traeen kept the race leader's yellow jersey despite being caught up behind the crash.

"I had to wait until this day to get this first chance to sprint in the Tour and to win it is unbelievable," said Kooij.

With the sprinters having had to wait until the fifth stage for their first chance at a bunch finish, there was understandably some extra tension in the peloton in the run in.
