Gabri Moroni has made the 2nd ascent of Adam Ondra's Goldrake, ~9a+, at Cornalba north of Bergamo in northern Italy.
Adam made the first ascent back in April 2010 and Gabri began working it a year or so later. This means Gabri worked it for... three years, which makes it his longest project ever. On the other hand he took a two year break after the first year... so, well, I don't know how you count these things.
... I just sent my "3years" project Goldrake!!! I still cannot believe it really happened!!
Here is Adam working the route prior to the FA. He was way skinnier back then.
