Jim Aikman: "Why in a day? Pushing through the night without sleeping... what's appealing about that kind of challenge?"
Siebe Vanhee: "Yeah. Very good question."
The latest episode of the Cutting Edge podcast came with bonus footage of Siebe Vanhee and Tommy Caldwell's all-free ascent on the east face of the Central Tower in Chile's Torres del Paine, offering a near complete visual of the terrain this team was up against.

On this month's edition of the Cutting Edge podcast, host Jim Aikman interviews Tommy Caldwell and Siebe Vanhee on their single day all free ascent of Torre Central with some extra intel and context from Ben Ditto, who was on the first free ascent of the South African Route in 2009.
