The 30th annual Duck Derby is being held on Sunday.
Hosted by the Lions Club of Maidenhead, the popular event will see thousands of plastic ducks float down the River Thames.
The Maidenhead Sea Cadets will release the racing birds at Ray Mill Island below Boulters Lock and then collect them, including the winning duck, whose owner will win a cash prize of £250.
This year the event will be merging with the Prince Phillip Challenge Trophy which starts at 2pm and will see the Maidenhead Sea Cadets and Windsor Sea Cadets battle it out for a trophy by competing in a boat, canoe and raft race.
Stalls will be set up around the area and there will also be a bouncy castle, fun train and a puppet show.
Ducks can be bought for £1 from the Nicholsons Centre today and tomorrow, or prior to the derby which starts at 4.30pm.
All the proceeds will go to charity.
