Comedian John Bishop has begun his epic triathlon to raise money for the BBC charity Sport Relief.
The 45-year-old set off on his bike from the Eiffel Tower in Paris on Monday morning.
He aims to cycle 85 miles (137km) to the coast in less than 24 hours, he will then row across the English Channel.
The final leg of the sporting feat will see him run three marathons in three days, finishing in London on Friday.
Just before he kicked off the challenge, he said: “I am not sure how I’m feeling really right now, it feels a bit like I am in a Mission Impossible movie with the Eiffel Tower behind me.
“I just need to get my head down and get a few miles under my belt.”
The comic from Liverpool, will be joined along the way by various celebrity friends, including Dermot O’Leary, Frank Skinner and Robbie Savage.
His trainer Greg Whyte, said: “The cycle alone is an extremely long distance to cover in less than 24 hours, even for an experienced ultra-endurance athlete.”
