Organisers of the World Naked Bike Ride in Cambridge have put a call out for someone to lead the event.
Due to work commitments, current ride leader Joe Fallowell fears he may not be able to attend.
Writing on the event's Facebook page, a plea has been made to find a replacement for Joe in the next six days.
A post this morning (May 6) said: "Cambridge WNBR needs help. We are looking for a new ride leader as Joe Fallowell has had to stand down.
Due to unforeseen circumstances. We need to find someone in the next six days."
Speaking to the News, Joe said the June 16 ride would go ahead regardless and still hoped he would be there.
A possible new ride leader would be in charge of cyclists taking part in the annual event in Cambridge.
Joe said that the ideal candidate would have experience of taking part in previous rides.
"There's no other requirements, other than they have an interest in what the protest is about," he added.
WNBR events are held across the country to highlight the vulnerability of cyclists in built up areas and the problem of pollution caused by motorised transport.
What is the World Naked Bike Ride?
Its a series of events held around the world where naked cyclists hit the streets in a protest against car culture and to raise awareness of the vulnerability of cyclists.
In the UK, similar events are being held in Kent, Essex, London, Manchester and Scotland.
Where is it in Cambridge?
Last year's event started at Parker's Piece and took an eight mile circular route around the city centre.
But a change in organisers for this year's ride will see a new route introduced, starting from Midsummer Common.
When is it?
The next ride in Cambridge is due to take place on June 16, 2018.
What are the rules?
Full nudity is optional – you can choose to take part naked, just wearing shorts, or even a swimming costume.
Will you be arrested?
No, it is legal to be naked in public in the UK as long as you are not doing it in a sexual context and with "the intention of causing distress, alarm or outrage”.
How do you take part?
You can keep up to date via the event Facebook page.
