BURSTAdam Ondra has completed his second flash of a V15 boulder with his ascent of The Lion’s Share in Switzerland. The line was first climbed by Aidan Roberts in 2023, who suggested that it “perhaps feels like 8C [V15] or 8C+ [V16].”
The Lion’s Share was subsequently repeated in 2025 by Jakob Schubert, Matt Fultz, and Sam Weir, all of whom graded it V15. Ondra shared his excitement: “Still buzzing from my second 8C flash! This time, Lion’s Share in Switzerland, which could be my hardest boulder flash ever… I still have a few more 8C candidates on my list for the next few days. I hope more will come.”
On Nov. 11, 2025, Ondra also flashed Foundation’s Edge V15 in Valais, Switzerland, and came very close to flashing another V15 that day, Big Nose. After flashing Foundation’s Edge, he reflected: “Some years ago, I would never have thought I’d be capable of flashing 8C. I never considered trying one. However, this winter, after flashing some 8Bs with margin, I began considering this option. I had this particular problem in mind as a good candidate.”
Ondra’s flash of Foundation’s Edge made him the third climber ever to flash the grade, and only the second to flash this particular problem. Yannick Flohé achieved the first-ever V15 flash in July 2025 with his first-go ascent of Foundation’s Edge. The following month, Jules Marchaland flashed Power of Now Direct in Magic Wood. Ondra was already considering attempting a groundbreaking V15 flash, and he admitted that hearing about Flohé’s success only fuelled his motivation.
Ondra is widely regarded as one of the best climbers in history, with groundbreaking ascents across all disciplines of climbing. He has repeatedly pushed the limits of difficulty, holding the hardest-ever sport climbing flash (Supercrackinette 5.15a), the hardest trad flash (Lexicon E11), and made the second ascent of Dawn Wall on El Capitan.
