This Col is one of the most famous in the world due to its frequent inclusion in the Tour de France (78 times since 1910 and 47 in the last 60 years)

In 2007, the Tour de France crossed the Col de Peyresourde on stage 15, joining the climb at Saint-Aventin (5.5 km from Bagnères de Luchon) after descending from the Port de Balès. This stage was selected for the 2007 L'Étape du Tour, in which amateur and club riders ride over a full stage of the tour.

The col was crossed twice in the 2012 Tour de France, firstly on Stage 16 from Pau to Bagnères-de-Luchon, when it was ranked a Category 1 climb, and again on the following day, when it was unranked, with the stage continuing on to the ski station at nearby Peyragudes.It was used again in the 2016 Tour de France on Stage 8, from Pau to Bagnères-de-Luchon, which saw eventual race winner Chris Froome make a daring descent attack from the top of the Col that caught many of his main rivals off guard, resulting in a solo stage victory.  https://en.wikipedia.org/wiki/Col_de_Peyresourde
