People with a good eye and a skilled hand are being invited to sign up for the All England Stone Skimming Championships.
The event, which is open to amateurs and international champions, takes place on 22 August on Windermere.
Competitors must make a stone skip on the surface of the water at least three times, with the winner making the longest throw.
Entry costs £3 for adults, £1 for a child and £10 for a team of up to four people.
Competitors get three stones, from a selection provided by the organisers, and skims must stay within lanes laid out in the water.
