While most boulderers focus on difficult movements close to the ground, Nina Williams has set her sights higher. Follow her rise as she astounds the climbing world with some spectacular ascents.

Nina Williams hones in on an outrageous new objective: a 15m-tall boulder called Too Big to Flail in California, which was first climbed by the world’s best free soloist, Alex Honnold.

Alex Honnold and Tommy Caldwell introduce us to one of the most coveted prizes in the climbing world: the speed record on The Nose route up the 915m El Capitan in Yosemite, California.

The race up The Nose heats up. While Alex Honnold knows the ropes and is pushing for perfection, Tommy Caldwell is new to speed climbing and the learning curve is as steep as the wall itself.

After weeks of practice and more than a few mishaps, Alex Honnold and Tommy Caldwell begin their attempt at the record. Onlookers hold their breath as the two rip up the face at breakneck speed.
