Shipquay Street Slide On: On the slippery slope for charity Cancer Research UK
Slipping in the street - especially one that's among the steepest in Europe - isn't normally a good idea.
But citizens and visitors to Londonderry's Shipquay Street have splashed out for a good cause - to raise funds for Cancer Research UK.
Over the weekend, there were three lanes available for the event which Cancer Research UK dubbed 'Slide On'.
Scores of people turned up to take on the challenge, and many more to cheer them on.
Perhaps because they are already well used to slippery slopes, namesake politicians Mark Durkan, Foyle MP and his Environment Minister nephew Mark H Durkan, were among the first to take the plunge.
They were joined by the city's mayor, Brendan Stevenson, and local priest Fr Paddy O'Kane, who donned a wetsuit for the charity challenge.
Altnagelvin Hospital sent down a team of doctors and nurses – not in case of injuries but to take part in the slide themselves.
Sharon Arbuckle of Cancer Research, said: "It's one of Europe's steepest streets.
"When you say to people, 'imagine Shipquay Street, imagine a waterslide', people immediately say, 'I want to do that!'
"It's a slippery street to slide upon. It's about taking part in something that's amazing fun for a great cause."
