Former London Warriors defensive back Vernon Kay has raised more than £5m for Children in Need after completing his ultra-marathon.

The BBC Radio 2 presenter ran from Leicester to Bolton - a distance of 116 miles - over four days.

"I'm absolutely exhausted, absolutely spent, physically, mentally," Kay said as he crossed the finish line just before 10.15am on Friday.

The American football fan, who first joined the Manchester Allstars aged 13 and later became a British American Football champion with the Warriors, added jokingly: "Is there anyone here who can replace a knee?"

The Children in Need TV audience chanted his name as he came out on stage and learned the latest total raised for his efforts. The challenge saw him stop off at some local landmarks in his hometown of Bolton, including his old school, before reaching the finish line.

"I'm so glad I went to St Joseph's first because that was a real boost," Kay said. "It just really elevates you... that's the pick-me-up I needed.

"It's been one of the most painful and joyous experiences I've ever had. People we've met along away. We've met some brilliant people who've donated all they can.

"It was just one foot in front of the other, that's what it was, and we've had a great team who've been absolutely brilliant, pushing me along and motivating me."

Children in Need, the BBC charity which helps improve the lives of disadvantaged children and young people around the UK, has raised more than £1bn for charities and projects since its first major appeal in 1980.
