Stefano Ghisolfi and Will Bosi Go Head-to-Head on Cracks

The two joined Pete Whittaker for some crack training in Tom Randall's famous cellar

Top Italian sport climber Stefano Ghisolfi recently travelled to the U.K. to train cracks with Pete Whittaker, one half of the Wide Boyz duo. Whittaker took Ghisolfi down to Tom Randall’s famous crack cellar to work technique on a wide range of hand and foot crack sizes.

Ghisolfi was joined by top Scottish climber Will Bosi for some crack challenges. Along with Whittaker, the pair tried crack boulder problems, timed one-arm hand jam hangs, and a “route” graded around 5.13c. A new video was just released of these crack challenges, and you’ll likely be surprised at how well Ghisolfi and Bosi do.

Whittaker and Ghisolfi originally met many months ago by video call when Ghisolfi was first exploring Adam Ondra’s Silence 5.15d. Ghisolfi was looking for some jamming advice for the route’s extremely difficult crack boulder problem. Who better to call than the world’s foremost crack technique expert, Whittaker. He’s even written a book on the subject.

Ghisolfi is one of the world’s best sport climbers. He has climbed four 5.15c’s: Excalibur in Arco, Perfecto Mundo in Margalef, Change in Flatanger, and Bibliographie in Céüse. In 2022, he repeated Adam Ondra’s Move 5.15b, and put up two 5.15b’s of his own in Italy, The Lonely Mountain and L’arenauta. He was also the 2021 IFSC Lead World Cup winner.

While in the U.K., Ghisolfi also spent a day working the moves on the now famous Burden of Dreams V17 replica with Bosi. Bosi is now off in Finland working the real thing. In October, Bosi repeated Shawn Raboutou’s Alphane V17. In 2022 alone, he climbed eleven V14’s, twelve V15’s, two V16’s, and one V17.
