Alex Megos never met a route he couldn’t climb in short order—until he encountered Bibliographie, an unclimbed route at the French super-crag, Céüse. In 2017, Megos first tried the route that would become his three-year project. On the path to the send he encountered doubts and injuries and qualified for the Olympics. It wasn’t until COVID turned the world upside down that he was able to return to Céüse and close the books on one of the hardest routes ever climbed. After completing the first ascent, Megos graded Bibiliographie 5.15d, making it the second 5.15d ever after Adam Ondra’s Silence.
