Spare a thought to think of Ben Fogle, poor lamb.
The intrepid adventure has been scorched in the Sahara, frozen in the South Pole and splashed about in the Atlantic. But now he has to take on his biggest fear: heights.
He'll be climbing up Utah's Castleton Tower as well as leaping into a solo skydive in Australia. Click on our clip to see real fear in Ben's eyes, and a cry of distress to rival Chewbacca's. Really.
So far we've seen Ben descend into ice caves, row on the Atlantic and even reach the South Pole.
So, this new challenge, a bike ride, should be a wheelie in the park, right?
Alas, no. Fool-hardy, sorry, dare-devil Ben will be cycling for a gruelling 24 hours across the US desert. Imagine the saddle-sore!
Still, we can't get enough of the affable lad's trails and tribulations. Check our clip to find out more.
Ben's adventures this week are all about pushing himself out of his comfort zone. For us, that means choosing a white chunky Kit Kat rather than milk but things are a little different for Ben.
He's lowering himself into the heart of a glacier, knowing that if his rope fails, he'll be carried away on an icy underground river.
We're shivering just thinking about it. But we're happy to watch, Kit Kat in hand.
Ben kicks off his Year of Adventures by tackling one of the world's toughest races, The Anaconda: a run, bike, kayak and swim through the unforgiving Australian wilderness.
As you'll see from our clip, Ben needs to sharpen up his skills before he heads down under, so what better way than a swim across an infamous stretch of water...
