Article says it took him 10 days,3 tries each day. Got another question though. On the bigup blog it says:
"Chris says the bottom section is probably 9a on its own, and super bouldery. Then you have a sloping shake-out followed by an 8c+ endurance route."
So as I take it a hold broke in the upper 8c+ section, making it 9a. But what about the lower section? Another broken hold or does Adam just think it's rather 9a+ than 9a?
Anyway, incredible achievement. Imagine what this guy can do if he dedicates as much time to a project as Sharma does...
