Watch Stefano Ghisolfi climb Ground Zero, the famous 5.14d at Tetto di Sarre (Sarre Roof) in Aosta Valley, first redpointed by Alberto Gnerro on Sept. 11 2002. The route has had a number of repeat ascents.
Gnerro said of his send, “Ground Zero is a name that evokes sad memories, but for me – on this very particular day and its strange atmosphere – this route will just be a nice memory and a great gift that this sport has given me. Even when it’s difficult to believe in yourself. I have no idea how hard Ground Zero is, but I think it’s harder than Avaro. Those who repeat it will let us know.”
