On-bike cameras give an idea of what the riders experienced on Alpe d'Huez on stage 20 of the 2015 Tour de France

On-bike footage recorded by riders during stage 20 of the 2015 Tour de France shows the huge number of fans lining the roadside on Alpe d’Huez.

There are few sports that enable fans to get so close to their heroes, and while the vast majority of spectators respect the riders and are there to have fun, you can clearly see a minority getting too close for comfort.

The already narrow, hairpin-strewn road to the top of the mountain is rendered ever more narrow with people crammed in at every available opportunity.

The most rowdy part is the famous ‘Dutch corner’ which turns orange every year when the Tour visits the climb as fans from the Netherlands arrive en masse to camp out and make it a festival atmosphere. Cheers, flares, fancy dress and flags make it quite a spectacle.

Despite the number of people on the mountain – estimated in previous years to be around one million – there were very few reported incidents, although race leader Chris Froome (Team Sky) did get spat at again.

Home fans had plenty to cheer about, with Frenchman Thibaut Pinot (FDJ) taking the stage victory as Froome all but secured the overall race win ahead of Sunday’s final stage to Paris.
