The Cutting Edge

On February 11, Erwan Legrand—only 17 at the time, and barefoot!—took down one of the longest-standing open projects in the world: Le Bombé Bleu at Buoux, France. Bolted on the La Plage sector in 1991 by Marc Le Menestrel, the 100-foot route features a notoriously difficult precision dyno on its blue-streaked bulge, followed by ferocious tugging on tiny pockets, all clocking in at a lofty 5.15b. Famously, Le Menestrel had opened the route to the community as long as it was left in its natural state, a vision of what climbing might someday become and a challenge for future generations. Thirty-five years later, Legrand—the son of legendary French climber François Legrand—met that challenge with style.

Join host Jim Aikman as he talks with Erwan Legrand about his remarkable barefoot redpoint, as well as U.K. icon Ben Moon—one of the route’s early suitors—and American Climbing Journal Editor Matt Samet, who interviewed Legrand about Le Bombé Bleu for the 2027 ACJ.

Preview the Cutting Edge's eighth season, featuring interviews with climbing legends like Colin Haley, Sasha DiGiulian, Tommy Caldwell, Benjamin Védrines, and many more. Tune in for monthly episodes to hear the stories behind first ascents, first-person accounts of recent expeditions, and climbing history that puts each climb in context.

The east face of the Central Tower in Chile's Torres del Paine is one of the great walls of the world. The first route up the face, climbed in 1973 and 1974 by a South African team, had only been freed twice. In February, Belgian Siebe Vanhee (a veteran of two other free ascents on the Central Tower) and American Tommy Caldwell (a newcomer to Torres del Paine but not to Patagonia) completed the third free ascent in remarkable style. On their third attempt, the two climbers raced up the 1,200-meter 5.12 route in exactly 24 hours—in an area where most big-wall ascents take weeks. Host Jim Aikman interviewed both climbers, as well as American Ben Ditto, who was on the first free ascent of the South African Route back in 2009. It's an episode about risk, the ups and downs of multiple efforts on a serious objective, and a partnership that perfectly balances the strengths of two amazing climbers.

In March 2025, the Bay Area–based climber Katie Lamb snagged the fourth ascent of Yosemite's most difficult boulder problem, The Dark Side, an unrelenting V16 on small crimps and dire slopers on the Thriller Boulder in Camp 4. In so doing, she became the first woman to climb the grade, but there's a catch: Back in summer 2023, Lamb had already done a V16, a problem called Box Therapy in Colorado—it's just that it was later downgraded to V15. In a complex and nuanced discussion on the state of the art in bouldering—and the evolution of the grading scales we use to classify these ascents—host Jim Aikman talks with Lamb about the passion, hard work, and tactics that went into her ticks. And he interviews The Dark Side's first ascensionist Carlo Traversi, a driving force behind modern Yosemite bouldering, as well as American Climbing Journal Editor Matt Samet, who worked with Lamb on her feature in the upcoming journal, "A Walk on the Dark Side."

One of the highlights of last fall's Nepal season was the first ascent of 7,468-meter Jannu East by French climbers Nicolas Jean and Benjamin Védrines, on their second attempt in two years. In this special episode of the Cutting Edge, Ben Védrines shares the full story of his two expeditions to Jannu, the physical and mental preparation, a "warm up" first ascent on 6,800-meter Anidesh Chuli, and the rapid ascent of Jannu East itself. American alpinist Steve House, a leading protagonist of single-push alpine ascents in the early 2000s and a top coach today, gives his perspective on the training and psychological aspects behind the French climbs. American Alpine Journal editor Dougald MacDonald unpacks the history of climbing on Jannu. There's a lot to share, so we're offering a special extended episode....enjoy!
