Are you up for the challenge?
For Sport Relief 2008 we're asking you to do something sporty and raise cash at the same time.
It's too late to sign up to take part in the event. But those who are running would love you to cheer them on.
Why not head down to the Victoria Embankment in Nottingham on Sunday 16 March 2008 and do just that.
As a Nottingham Miler, you can look forward to a fun day out while raising mountains of cash.
It all begins on the banks of the River Trent at Victoria Embankment where you can get limbered up and enjoy the atmosphere before your Mile kicks off.
Join thousands of runners, with crowds cheering you on as you make your way along the embankment, taking in the picturesque scenery as you go.
When you cross the finishing line, you'll feel fantastic and, by getting sponsored, you'll have helped to change the world by miles too!
Famous Nottinghamshire faces Nigel Clough, Frank Clarke and Chris Broad are all taking part.
If you can't make it down to the race itself, check out your friends and family running for charity on The Mile Show, BBC1 on Sunday (3-5pm).
