Will Bosi is a climber from Edinburgh in Scotland. He started out as a competition climber, first progressing through national competitions and then European youth comps where he had a string of podium finishes. He struggled somewhat to replicate the successes of the youth comps in the adult circuit, with his performance being two 4th place finishes in 2019.

Since retiring from comps he has turned to sport climbing and bouldering outdoors, where he has been extremely successful. In 2020 he became the second British climber to climb 9b sport with his repeat of La Capella. He then replicated this success in 2021 with hard first ascents and repeats including among others:

Since 2022 he has focused more on bouldering, where he has also excelled. For example he flashed Charizard 8B+ and, as of 2024, has repeated three 9A boulders:

40 sessions.

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]

First ascent.

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]

Alphane 9A Boulder | worked 31st Oct 2022
Third ascent. Around 13 sessions.

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]

Return of the Sleepwalker 9A Boulder | worked 19th Feb 2024
Second ascent. 12 sessions.

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]

First ascent. 8 sessions.

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]

Free at Last 9a+ Lead | worked 25th Jun 2022 9a+
First ascent.

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]

40 sessions.

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]

Alphane 9A Boulder | worked 31st Oct 2022 9A (soft)
Third ascent. Around 13 sessions.

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]
