Dancers from schools around the Bradford district will take part in a relay "tapathon" in aid of the Roy Castle Lung Cancer Foundation.
Mr Castle's widow, Fiona Castle, will be attending the event, at Halifax's North Bridge Leisure Centre.
Twenty dancing schools, featuring hundreds of tap dancers aged from three to 83, will keep tapping between 10am and 4.30pm on Sunday, January 20.
Taking part this year will be the Gainsborough Stage School and Kath's Tappers from Bradford, and the Janet Austin Tappers and Elwyn School of Dance from Brighouse.
The event is marking its 12th anniversary and since it stared has raised £123,000 to fight lung cancer.
The charity was set up in the name of entertainer and dancer Roy Castle, who died of lung cancer in 2004.
