What's it like to cycle Alpe d'Huez?
5 live BeSpoke's OJ Borg attempts Alpe d'Huez: dubbed cycling's 'Hollywood climb'.
The mountain, with its 8.5% average gradient and 21 bends, could play a key role in the 2015 Tour de France. The 13.2km climb comes just a day from the end, meaning this year's race could be decided on its slopes.
OJ attempts the mountain with cycling journalist and 'Alpe d'Huez' and 'The Monuments' author Peter Cossins, who talks through the its colourful history, and local guide Phil Daniels.
