A former professional footballer is set to "run" a marathon at a snail's pace for charity - dressed as one.
Lloyd Scott is going to crawl the London Marathon on April 17 dressed as Magic Roundabout character Brian the Snail.
Mr Scott has raised more than £5 million for charity by running marathons in unusual outfits.
He revealed his choice of costume for this year's London Marathon at a photocall at the National Maritime Museum.
The 49-year-old, from Rainham, Essex, who played for Watford, Blackpool and Leyton Orient, said: "I am going to be crawling the course.
"There is a sledge inside the outfit and I will drag myself around with my arms. It's going to be a slow and painful process."
He has run the 26.2-mile marathon in six different costumes including an antique diving suit and a St George and Dragon outfit. He has also cycled across Australia on a penny-farthing, completed an underwater marathon in Loch Ness, Scotland, and undertaken a number of other crazy challenges.
He added: "It's going to take me around one mile per day. That will be the slowest I have ever completed the marathon in.
"I would rank it right up there as one of the hardest. When I have practised, it has been a painful drag. But it is worth it for all the money we will donate."
Mr Scott, who fought off leukaemia more than 20 years ago, hopes to raise at least £20,000 for Action for Kids, which helps disabled children.
