The pair will lead two two teams of celebrities in sporting challenges at London's Queen Elizabeth Olympic Park on 21 March.

Among those joining Lord Coe will be BBC Radio 1 presenter Greg James, pop star Olly Murs, comedy actress Sally Phillips and Winter Olympic skeleton gold medallist Amy Williams.

Bishop's team will include Olympic boxing gold medallist Nicola Adams, former England cricketer Andrew Flintoff, BBC Radio 1 Breakfast Show host Nick Grimshaw, comedian and presenter Patrick Kielty and TV presenter Helen Skelton.

The teams will take part in events, including rhythmic gymnastics, track cycling and swimming and the event will be broadcast live on the BBC.

Bishop, 47, said: "Am I intimidated by going up against Sebastian Coe? No, bring it on!"

Bishop completes his 2012 Sport Relief challenge

Coe won gold in the 1500m, and silver in the 800m, at both the 1980 and 1984 Olympics.

He later led London's successful bid for the 2012 Olympics and was subsequently made chairman of Games organiser Locog.

The 57-year-old said: "I spent the best part of 10 years preoccupied with the planning and delivery of London 2012.

"Not once did I imagine that less than two years later I would find myself back at the park competing.

"I hear John Bishop has quite a competitive streak but I know these venues inside out - something that, probably unrealistically, I am hoping will play to my advantage."

In 2012, Bishop completed a five-day challenge to cycle, row and run the 290 miles from Paris to London in aid of Sport Relief, a feat he described as "the biggest physical challenge of my life".

The 2014 Sport Relief Weekend takes place from 21-23 March and money raised will help some of the poorest and most disadvantaged people in the UK and around the world.

Last week, TV presenter Davina McCall completed a 500-mile triathlon challenge from Edinburgh to London, raising more than £760,000.
