Bear Grylls is probably the most recognisable face of adventure on the planet.

He is a former 21 SAS soldier, who went on to become one of the youngest ever climbers of Mt Everest, despite breaking his back in a free-fall accident only months earlier.

From Everest he has gone on to host more extreme adventure TV shows across more global networks than anyone in history.

Bear's shows include the legendary Discovery channel show MAN Vs WILD and the hit show RUNNING WILD with Bear Grylls, now in its eighth season on National Geographic Channel and Disney Plus.

His guests have included: Will Ferrell, Bradley Cooper, Roger Federer, Julia Roberts, plus President Obama, Prime Minister Modi of India and many others.

Bear currently hosts the hit Netflix series Bear Hunt where he takes 12 celebrities to the jungle, trains them up, before hunting and tracking them down. This became the Number One show on Netflix.

He is a double BAFTA & EMMY winner, a family man, and a No. 1 bestselling author who has sold over 20 million books.

He is the Honorary Colonel to the British Royal Marine Commandos, & the first ever Chief Ambassador to 55 million young Scouts worldwide.

He is married to Shara with 3 sons. They live part of the year off grid on a small remote Welsh island.
