Matty Hong, who just did La Rambla 9a+, reports on Instagram that he has done another one, Joe Kinder's Joe Mama in Oliana. He did his first 9a+, Papichulo, one year ago. He also did 25 routes 8b+ and harder in 2016 and received the Sport Climbing Piton from Climbing.
How many sessions did it take and how can you best explain your step up in grades?
It took me 5 days of work. I've been climbing more than ever this past year, I think just being able to spend more time outdoors has really helped my climbing and motivation. Finishing school was a big part of this.
