"Foundation's Edge" (8C) by William Bosi

After the World Championships, the young Scot William Bosi was now on the move in Switzerland without a rope. The result was quite an impressive ticklist. Among other things, Will manages, after Ulls de Bruixa, his third 8C boulder with “Foundation’s Edge” 8C in the Swiss bouldering crag of Fionnay. It was the 6th ascent of the Dave Graham Boulder from 2013.

The first ascenter Giuliano Cameroni graded the boulder “Hazel Grace” also with 8C by  and the first repeater Nalle Hukkataival also approved the boulder in this grade.

Very excited to have had a trip out to Swiss after the world champs and be able to tick off some dream boulders! Tick list below;
Foundation’s Edge 8C
Hazel Grace 8B+ (perhaps 8C) (with new sit start)
Highlander 8B+
Gepresster Hase 8B+
Scarred for Life 8B+
Red snapper 8A+ flash
Dulcifer 8A+ flash

In spring, Will caused a sensation with the first ascent of “King Capella” (9b+). He is only the fifth climber after Adam Ondra, Alexander Megos, Jakob Schubert, Stefano Ghisolfi and Chris Sharma to climb a 9b+ route and is, of course, the first Briton.

    Nicht sein erster 8C Boulder. Weiss zumindest von Serenata und Practice of the wild.

      Danke Mathias, Seine Begehung von “Serenata” haben wir echt nicht mitbekommen. Aber er war auch mit seinem, bisher unwiederholten, eigenen Boulder “Ulls de Bruixa” im Grad 8C unterwegs.”Practice of the wild” gilt mittlerweile als 8B+/C. Wir korrigieren es mal.
