La Dura Dura

[5][3] The pair suspended their work until the end of that year when Ondra made five trips over nine weeks to Oliana, and eventually free climbed the route on 7 February 2013.

[3][9][10] This was amplified when climbing filmmaker Josh Lowell produced a film in 2012 documenting their collaboration on the route (part of Reel Rock 7),[11] which was subsequently updated in 2013 to include their ascents (reissued in 2014 as La Dura Complete).

[5] The most technically difficult part is the first 10-metre section, which Ondra and Sharma described as "really bouldery" with 15 moves that would constitute a 9b/b+  climb on their own.

[8] Ondra described this first section as requiring big reaches on crimpy holds and underclings, which lead to a "huge span rightward onto a crimp, and dyno from there onto a good hueco".

[8] After the kneebar, the next 6-metres are described as "really intense", with "a shoulder-breaking dyno into big reaches on pinches and crimps with two 'stop' moves right below the jug".

[10] On 19 June 2022, a wildfire broke out in a nearby field that badly affected the Oliana crag that holds La Dura Dura with reports of holds breaking off and lower sections completely destroyed; the full extent of the damage is as yet unclear.

[17][18] However, in a series of Instagram posts released in early 2024, Chris Sharma indicated that he had resumed his efforts on his longstanding project "Le Blond."
