American rock climber Alex Honnold hit the headlines in 2017 when he became the first person to ascend the 3,000ft El Capitan rock face in Yosemite National Park in California without ropes or safety equipment – a stunning feat captured in the Oscar-winning documentary Free Solo.

Now, in a new three-part series on National Geographic, Honnold takes on another daunting and dangerous challenge as he attempts to scale Ingmikortilaq, a 3,750ft Arctic sea cliff in Greenland.
