On-bike footage from stage 11 of the 2015 Tour de France shows riders' skill in tackling the high mountains

On-bike footage shot by cameras mounted on riders’ bikes during stage 11 of the 2015 Tour de France shows just how quickly and adeptly pro riders tackle the long, sweeping roads of the Pyrenean mountains.

With the peloton touching 100kmh (60mph) and beyond on the descents there is little margin for error, particularly when there are other riders surrounding you and not much stopping you from going off the road.

The iconic climbs of the Col d’Aspin and Col du Tourmalet were tackled during the 188km stage on Wednesday, which travelled from Pau to Cauterets.

As ever, large crowds gathered near the summits of the major climbs to watch their Tour heroes first hand. From the footage, you can see the riders squeezing between the mountain-top spectators.

The descents very rarely have many fans by the roadside, and so the bar-mounted cameras afford fantastic views of the scenery on a clear and blisteringly hot day.

Polish Tinkoff-Saxo rider Rafal Majka won the stage after attacking from the day’s escape group. Irishman Daniel Martin (Cannondale-Garmin) gave chase to place second. The overall race contenders were happy to call a semi-truce, with only defending Tour champion Vincenzo Nibali (Astana) dropping off the pace and losing time to race leader Chris Froome (Team Sky).
