Biographie, a F8c+ route at Ceuse that was extended by Chris Sharma to give an overall grade of F9a+, is one of the most beautiful extreme sport routes in the world.
Sharma named his extension Realisation but the locals still call the route Biographie since the custom in France is that the person who puts the bolts in is the one who is allowed to name the route. In this case the bolts were placed by Jean-Christophe Lafaille who gave it the name. Arnaud Petite managed to climb 2/3 of the route and put a new chain in. Sharma then extended it and renamed it.
