"In 2007 we smashed the Singapore World Record by racing 165,000 yellow plastic ducks down the river Thames and raised over £100,000 for 440 UK charities – thank you so much for your support and generosity.

For 2008 we want to do it bigger and better; we will be attempting to race a quarter of a million of our little yellow friends down the 1 kilometre race course! This will break the record we already hold, and prove to the rest of the duck racing world that Great Britain does it better!!!

On Sunday the 31st of August the ducks will take to the water on our dedicated course at Molesey Lock, near Hampton Court Palace.
It is just £2 to adopt a duck*. There are 30 top prizes, and first prize is a whopping £10,000. (*your £2 includes a donation to our 3 lead charities, additional donations can be made to support your chosen charity)."
