"David Walliams has taken going the extra mile for Sport Relief that little bit further – 21 miles further across the English Channel to be precise.
Braving oil tankers, giant waves, slimy seaweed not to mention all sorts of deeply unsavoury objects too, the Little Britain star is aiming the swim to France…but he needs your help to do it.
What You Can Do
Over the next five weeks while David finishes his training, we will be providing loads of ways for you to support this epic challenge and get involved with the Speedo Sport Relief Super Swim: from competitions and mobile downloads to exclusive clips and games."
You can sign up for updates and there's also a saucy pic of David in a swimsuit :)
