Bear Grylls is set to host a new ‘gruelling’ survival show for ITV. The two part-series will star rugby union player Jonny Wilkinson and former boxer, Nicola Adams.

The pair will face the harsh terrain of Dartmoor in a once in a lifetime experience to put their survival instincts to the test. Bear & Jonny Wilkinson’s Wild Adventure and Bear & Nicola Adams’ Wild Adventure will both be broadcast this spring.

During each episode, the TV adventurer, who owns the island of Ynys Tudwal Fawr (St Tudwal’s Island West) near Abersoch in Gwynedd will push the stars to their limits.

Jonny and Nicola will join Bear to face challenges from rock climbing, rappelling, abseiling to crossing ice-cold rivers. The stars will also learn the key basic survival skills necessary to get by in remote terrain like Dartmoor.

In addition to the physical challenge of the adventures, Bear will also have the chance to get to know his companions by speaking to them about their lives, achievements, key life moments, as well as their hopes for the future.

Also, Bear will be sourcing some wilderness survival food to sustain them through the journeys.

He said: “Both Jonny and Nicola are icons of their sports, and for me to be able to find out about their journey to stardom and their struggles along the way was a real privilege.

Jonny added: “Spending time with Bear, being challenged in so many ways, and sharing a few intense adventure experiences, was an absolute privilege. I’ll always remember this one!”

Nicola described it as a “surreal experience”. She said: “It’s a challenge I’ve always wanted to do and be a part of. I love getting out of my comfort zone but this was unlike anything I’ve done before. I’m grateful to Bear and the rest of the team for helping me through this and I can’t wait for everyone to see what we got up to.”
