Andrew Nolan is taking on Mount Everest. Yes, that Everest. The highest mountain on the planet at a staggering 8,848 metres above sea level.

He joined Katie live in studio to talk about preparing for the final and most dangerous challenge of the Seven Summits. Everest is the last one standing. Temperatures can drop to minus 40 degrees. Oxygen levels at the summit are so low it is often compared to being underwater. Every step feels like your body is fighting to survive.

So why would anyone choose to do it?

Andrew opens up about where this obsession began, the mental strength it takes to keep going when your body is screaming to stop, and the reality of what can go wrong at extreme altitude. From brutal training sessions to facing death in the so called death zone, nothing was off limits.

If you have ever wondered what pushes someone to risk everything for a few minutes on top of the world, this is the conversation you need to hear.

Hit play and step inside the mindset of a man about to take on Everest.
