8c+ (9a) and a 8b+ flash by William Bosi (18)
William Bosi, who has done two 9a's before, has sent Jungle Speed in Siurana confirming down grading suggestions to 8c+. "So pyched I managed to do this amazing route in a day." Hubble, the former 8c+ by Moon in 1990, took six sessions so Bosi's very quick ascent of Jungle Speed, once again confirms the grade inflation.
The 18 year old also did his first 8b+ flash by El Mรณn de Sofia where actually half the route was onsight as he only had beta for the first half.
What is the plan and ambition 2017?
I am here till the 22nd so I'll hopefully do some more stuff. I have been working on a film with Hot Aches Productions due out at the Kendal Film Festival this year so my goals are to get ticked some of the U.K.'s hardest routes. Still focusing on lead comps doing lots of the youth and some seniors.
