wanted to push myself to the next level. Where is that? I had to discover it. That was a big process in itself. So I bolted all these routes [in Spain]. And a lot of them ended up being that next level". The period saw Sharma bolt and free numerous new extreme -graded "King Lines", including (2008), Neanderthal (2009), and First Round First Minute (2011), each a major project in itself and since regarded as important classics, with Sharma saying "That's the thing about being on the cutting edge. You have to invent it". In 2011, Sharma invited the then 19-year-old climbing prodigy Adam Ondra, to try an Oliana route he had bolted in 2009 called La Dura Dura, which Sharma himself had given up on saying "I never saw myself being able to climb it.", and "I figured it would be for the next generation". For the next year, the two climbers worked the route in a collaborative process that saw Ondra make the first ascent in February 2013, and Sharma make the first repeat in March 2013. National Geographic called their collaboration 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. Both Ondra and Sharma declared the collaboration to be a very positive experience with Sharma saying post his March ascent: "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". Their collaboration was documented in Reel Rock 7 (2012), and La Dura Complete (2013). Post 2013 At , La Dura Dura would hold the rank of "world's hardest climb" until Ondra climbed Silence at in 2017, and while Sharma would put up several more "King Lines" over the next 5 years, it marked the high-point in terms of his hardest route. In 2015, he freed El Bon Combat, considered at the time to be close to , and in 2016 he soloed Alesha, the world's first DWS route. One of Sharma's last known projects was a potential route in Oliana beside La Dura Dura called Le Blonde, named in memory of Patrick Edlinger; it remains unfinished. Legacy Sharma is widely considered one of the greatest and most important rock climbers in the history of the sport. Sharma took on the title of "world's strongest
