Who'd have thought that gorgeous model Nell McAndrew would have something in common with larger-than-life TV funnyman Johnny Vegas?

Both Nell and Johnny are supporting Butlins Swimathon 2005 and want everyone to know that time is running out to join them and thousands of others across the UK in the world's largest swimming fundraiser.

The massive event kicks off for charity in just four weeks time and hopes to raise £2 million for NCH, the children's charity, so the time has come to don that cossie and get active for a great cause.

Taking part in Butlins Swimathon couldn't be easier. You can register online at www.swimathon.org , phone the Butlins Swimathon hotline on 0845 36 700 36 or pick up an entry form from your local participating pool.

Also urging people to sign up is Olympic legend and Butlins Swimathon President Duncan Goodhew, who says: "This year you could really make a difference for NCH, the children's charity, by getting into the pool and turning your miles into smiles on the faces of children who need it the most, as well as getting fit and enjoying some exercise at the same time! I really do encourage everyone out there to get involved."

And the great news is you don't even have to be a great swimmer because Butlins Swimathon is open to swimmers of all ages and abilities, from those who may have just graduated from doggy paddle to others who think nothing of 100 lengths before breakfast.

Swimmers can choose from seven challenges ranging from 'Simply Swim', where the participant elects the distance they want to swim, to a 10,000 metre endurance marathon - which is not recommended for the faint-hearted!

There's even incentives to join up, including an online Personal Trainer designed by Speedo that is guaranteed to have you in good shape for the event, so now there's no excuse not to join Nell and Johnny!
