A toddler, who climbed his first mountain at two-weeks-old on his dad’s back, has become the youngest person ever to climb Britain’s highest mountains - aged just three years old.

Jaxon Krzysik took on the famous Three Peaks Challenge with his dad to raise money for his friend, Ralph Rowlands, who died aged two after suffering brain damage.

The young mountaineer's father, Cal Krzysik, 29, said Jaxon walked all the way up each peak unaided, but he did have to carry him back down.

“He loves his mountains, he loves rocks, he likes climbing on rocks. That’s just what he loves to do, to be honest with you,” Mr Krzysik told The Telegraph.
