32-year-old Czech climber Adam Ondra has flashed his hardest boulder to date, Foundation's Edge at Fionnay in Switzerland. Put up by Dave Graham in 2015, the problem is well-known amongst the world’s best to be flashable, and indeed it was flashed in June this year by Germany’s Yannick Flohé who, in doing so, became the first person in the world to flash 8C boulder.

Jules Marchaland followed suit in August on the Power of Now Direct at Magic Wood and now, having previously flashed 8B+, has upped his game in what he has described as a send the "felt effortless, pure perfection. Unbelievable moment."

Ondra wouldn't be Ondra without taking pushing things even further still and later that day he attempted to flash another 8C, Big Nose. Two 8C flashes in a day would have been a new, unheard of benchmark, but it wasn't to be and he had to settle with the send two tries later...
