Sport Relief is back on Saturday and it's even bigger than ever!
The event aims to raise money to help poor children in the UK and across the world.
Comedian David Walliams has already done his bit by swimming all the way from England to France.
And Sportround presenters Lizzie, Jake and Adam will be running in a special 4x400m relay race in Manchester on Saturday!
But are you doing anything for Sport Relief?
Perhaps you'll be taking part in one of the mile races?
Or maybe your school has organised an event to help raise some money?
Or will you just be watching the Sport Relief show on TV?

Sports Relief is so fun and cool as you raise money for good causes. It's great to have fun and to help people in the same time!
