A Castleton family and their dog will set off on Monday in their 1967 VW campervan which has a top speed of just 50mph to travel the coast of England in aid of the RNLI.
Fiona Knowles, husband Richard, daughter Charlotte with their spaniel Sam, hope to complete the trip in the vintage vehicle - nicknamed Lucy - in three weeks.
They will travel anti-clockwise along the coast visiting as many lifeboat stations as they can, collecting funds for the charity along the way.
The Knowles hope to raise more than £500 for the charity.
