Exactly 2 years after Stefano Ghisolfi made the first ascent!

The first go of the day everything went perfectly, I felt like I was floating through climb and arrived at my previous high point feeling strong. Setting up for the final hard move I was really confident but disaster struck and I just missed the hold and fell of I took an hour rest, warmed up and went again. This time I arrived at the rest feeling tired battling through the upper section but on the final crux I landed perfectly into the slot. Pumped out of my mind, I almost fell jumping to the jug but just about kept it together for the top out.

Second ascent of a 9b by a brit, and the first british repeat of an established 9b.

Three sessions just to work out the first sequence.

The long awaited second ascent after 4 years and 40 sessions.

Finally! This was by far and away my longest project on a route and I am so happy to clip the chains. It is so typical of the redpointing game that the route went down on the last go of the day with little expectation that I would send it! Full credit to Steve McClure on an amazing first ascent and for establishing a climb with such amazing moves. [1]

The climb is very similar to Hubble in a sense but the sequence of moves are a lot more complex and technically demanding. I was stuck for a while on the lower section but once I was able to unlock a sequence, the route came together really quickly for me. [2]

Although there seems to be a lot of holds from the floor, almost everything is an undercut or a side pull. This makes the climbing very technical as the feet are tiny! The climbing is also very intense and powerful as you cannot relax. [2]

Before the first ascent Will had been playing on the boulder with Dave Graham and trying some of the moves. At the time the line seemed too futuristic so he didn't dedicate to it.

After Shawn Raboutou made the first ascent Will got psyched on the line again and headed out with Aidan Roberts, initially just to try the line and then, when he made quick progress, to send it.

In terms of a grade, I personally felt that Honey Badger was more of a challenge for me and proposing a grade for that at the time was daunting as it was my first 8C+. At the cutting edge of climbing, grading feels so much more difficult as the margins are that much finer and personal strengths and preferences really come into play.

Is it 9A? Honestly, I do not know and as I gain more experience of climbing around this grade range I may have a better view, but it is a fantastic line established by Shawn [Raboutou] and I look forward to seeing more experienced climbers comment on where the grade sits. [2]

The long-awaited second ascent after 24 days of work, with 10 sessions on a replica created using 3d scans of the holds and then 14 sessions on the real thing.

12 sessions in total, including 3 spent on the stand start Sleepwalker, completed during a single trip to try the boulder.

In the last session before the send, everything just clicked. I was feeling confident, but as the weather forecast looked bleak with a storm closing in, I was only able to take one rest day before heading back out for another session. I still felt quite tired from the previous session so I was unsure about even trying it.

However, after warming up, the moves were feeling great and I decided to give it a go. The first attempt went perfectly up to the sloper but then I really messed up the next move through to the slot and almost dropped it. Somehow, I recovered and hit the last hard move perfectly. Pulling onto the slab was incredible and I had to take a minute to get my breath back before heading up to the top. [1]

I did one at Raven Tor, Wild South, which I tried a crazy amount of days, but I was ignoring a kneebar for a long time because I didn’t want there to be a kneebar there. Then one day, I tried a kneepad, and it worked really well. I gave that climb 8C because when I started trying the knee, it only took two sessions, and it didn’t feel as bad, but looking back I’m thinking it didn’t feel so bad because I’d spent so much time on the rest of the boulder. So I think that’s probably an 8C+. [2]

Will used different beta to Aidan (keeping the right heel in to match the left hand in) which he felt was more 8C than the 8C+ that Aidan proposed.

Will was close to climbing the problem on his second session, dropping it with his right hand in the slot and left hand on the sloper. He then did it on the first go of his third session.

Super happy to send this! Now onto the full line of Terranova :) Grade wise it felt like the hardest or joint hardest boulder ive done in the Czech so i think it deserves the C but time will tell

Will broke a foothold on his first go which made the sit unfeasible. However he then did the problem from a crouch start and suggested 8B+ for this.

Will used some different beta which he found a little easier than the original sequence.

Some of the holds have broken/deteriorated since Jana Švecová made the first ascent which is why Will suggested an upgrade.

Will was the first to repeat it post break and suggested the boulder was more on the 8B+ side now.

Yeah, it’s such a good problem! Learning the move took a while, but in the end, I didn’t quite hit the right hand. Still, I felt solid in the position and was able to sketch through to the top. Instead of using four fingers, I had to go with three, and when I hit that crimp, I fully crimped on it. At that point, I was just praying it wouldn’t rip and hoping for the best up there. I think it’s been three years since the hold broke, and I don’t think anyone has done that move until today. It’s a hard one—people have tried it, and from those I’ve spoken to who attempted it before and after the break, they say it’s a lot harder now. I never tried it before, so I can’t compare, but it definitely felt hard for the grade. With grit, when you finally send the climb, the sequence always seems to work out better and feels a bit easier. But to be honest, this one still felt pretty tough at the top. There aren’t many moves, and I suppose with a lot of good days and good skin, you could learn it quite well. Still, it felt hard. I was pulling really hard through the top. I definitely think it’s more than likely on the 8B+ side.
