It has a unique history of dedicated people doing extraordinary things to make a difference - from David Walliams’ swim across the English Channel, to Eddie Izzard’s amazing marathon a day around the UK.
And that's not to mention the thousands of incredible fundraisers who do something fun and active to raise cash and help make the world of difference.
All the money raised by the public is spent by Comic Reliefto help transform the lives of poor and vulnerable people,
both at home and across the world’s poorest countries.
So be a part of it…
Rise to the challenge for Sport Relief!
