What happens when Olympians take on Gladiators?

What happens when you bring together Olympic athletes, Gladiators, school kids and get them all to battle it out during one massive sports day?

Children from one lucky school got to find out after they were given the chance to take part in filming for BBC Sport ahead of the Paris Olympic Games.

There was a wheelbarrow race, sack showdown and even a three-legged sprint - complete with some very sneaky behaviour.

Newsround was given exclusive access to see how the film came together.
