The London Marathon will see an array of celebrities, sportspeople and everyday Brits taking part in the race.
Among the nearly 60,000 people joing the marathon will be Olympians Dame Laura Kenny and Sir Ben Ainslie, both running for charity.
Former Arsenal and England football captain Tony Adams, horse racing great AP McCoy and F1 racing driver Sebastian Vettel are also among the runners.
At least one cartoon character is also known to take part in the race – Daddy Pig, the father of popular children’s TV show character Peppa Pig.
He will race for the National Deaf Children’s Society, following the show’s storyline that son George Pig is moderately deaf.
