La Dura Dura

La Dura Dura is a 50 m sport climbing route on the multi-coloured limestone cliffs known as the Contrafort de Rumbau, which are part of the Roc de Rumbau mountain, that lies in Oliana, Spain. The route was bolted and developed by American climber Chris Sharma in 2009 who had almost given up believing he could climb it until a collaboration with Czech climber Adam Ondra led to Ondra climbing the route on 7 February 2013, followed by Sharma on 23 March 2013.

La Dura Dura became one of the first rock climbs in the world to achieve a grade of, and was the first consensus grade at that level (i.e. more than one climber agreed to it). The route has not been repeated since Ondra's and Sharma's 2013 ascents. Being two of the leading rock climbers in the world at that time, their unique collaboration was widely followed in the climbing media; it is an important route in rock climbing history. The cliff was badly damaged by a fire in 2022.

History
American climber Chris Sharma had been pushing the standards of sport climbing, freeing Realization in 2001, the first consensus, and then freeing Jumbo Love in 2008, the first consensus. Sharma bolted La Dura Dura in 2009, saying: "If you're going to spend so much time on something, the line must really be worthwhile and it's difficult to find something that is at your limit and also fits your style"; and also, that "it was a beautiful, if blank-looking, streak of blue and white limestone". Sharma became disillusioned at the feasibility of the route due to the tiny "crimper" moves on the first 10 metres of the route, and by 2011 had almost abandoned his project saying, "I figured it would be for the next generation".

Sharma invited Czech climber Adam Ondra to see if he could solve the route, and they spent early 2012 alternating belays and ideas on how to climb it, and in particular, the first part of the route where the bouldering grade was a near. 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. Ondra said that solving the crux 15-move bouldering problem at the start of the climb, took eight of the nine weeks. Sharma did the second ascent on 23 March 2013.

Ondra assigned a grade of to La Dura Dura saying that it was harder than any other  he had done at that time, and that it was also harder than his October 2012 ascent of Change (climb) in Flatanger, Norway, which he also proposed at  (thus at the time making Change the world's first 9b+; however, in 2022 it was downgraded). Ondra said that Change suited his style better and only took him five weeks to complete, whereas La Dura Dura was "more straightforward climbing, but you really need to get everything wired 100%", and that: "I'd say that for me La Dura Dura is a better achievement because it fits my style less". Sharma agreed with Ondra on the grade adding: "Well if Adam thinks it is 9b+ it probably is, he probably knows more about this grade than anybody so he's sure to be right".

The route caught the climbing world's imagination and attention, not only for its technical challenges and the likelihood that any successful ascent could see a breakthrough in the world's highest climbing grade but also for the unique collaboration between what were arguably the two strongest sport climbers in the world (Sharma, the 31-year old legend, and Ondra, the 20-year old prodigy). This was amplified when climbing filmmaker Josh Lowell produced a film in 2012 documenting their collaboration on the route (part of Reel Rock 7), which was subsequently updated in 2013 to include their ascents (reissued in 2014 as La Dura Complete). Both Ondra and Sharma declared the collaboration to be a very positive experience with Sharma saying post his March ascent: "I'd practically written the route off and when we decided to work it together he [Ondra] brought it back to life. It was a healthy process for both of us, we fed off each other's motivation and through him, I think I became a better climber myself".

Route
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 climb on their own. 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". In all, Ondra broke this first section into four separate boulder problems, that a separated from bolt-to-bolt, with approximately four moves for each one of them, and that had respective bouldering grades of:, , ,.

After the bouldering section is a 10-metre section with a 4-metre climb to a kneebar, which Ondra described as "super-awkward and tricky" and "Not a proper no-hands rest, but it is possible to cool down a little". 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". Both Ondra and Sharma took many falls in this section. This is the halfway stage but with all the cruxes and hardest climbing completed – the final 20-meters of climbing is at.

Legacy
La Dura Dura became the world's first repeated and thus confirmed climb (Ondra's Change was recorded as the first 9b+, and that route was not repeated until 2020 by Italian Stefano Ghisolfi who confirmed the grade); and for years it was listed as the "world's hardest climb" (Ondra had said it was harder than Change), until Ondra's 2017 ascent of Silence at. In August 2022, French climber Seb Bouin, and climbing partner of Ondra, made the third ascent of Change and felt the discovery of a kneebar graded it (5.15b/c), thus making La Dura Dura the world's first 9b+.

The climbing media have speculated on why La Dura Dura had not had a third ascent (even by 2022, when the 9b+ route from 2020, Bibliographie, was repeated twice). Both Sharma and Ondra, as well as being two of the world's best climbers, are also tall climbers with long reaches and this may make specific parts of the lower bouldering type cruxes harder for shorter climbers; others speculate that La Dura Dura is really closer to.

Outside called the effort a "near Shakespearean drama". After Ondra's ascent of La Dura Dura and Change, National Geographic added Ondra to this 2013 list of "Adventurers of the Year", and noted the significance of Ondra and Sharma's collaboration as being a defining moment in the sport of rock climbing, when the title of "world's best climber" had begun to pass from one generation to the next.

Wildfire
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. 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." Despite Le Blond being immediately adjacent to La Dura Dura on its right, no mention was made of damage to the crag.
