Llangollen Operatic Society's charity "Nun Run" is this coming Sunday, starting at 10.30am from Llangollen Sports Club.
Organiser Lousa Jones said: "We have had a hugely positive response to this event from the local community so far and I am confident we are on track to raise a good sum to split between Leonard Cheshire Disability and the Society, which will be greatly appreciated on both sides.
"There are about 25 society members and friends taking part, the majority of whom will be in costume.
"So anyone out for a walk on Sunday morning might well catch a glimpse of the Pope on the Panorama, a Deacon on Dinbren Road or even a few Sisters on Sun Bank.
"Needless to say, we are all praying hard for clement weather."
* If anyone would still like to support the event by making a donation, they can email email@example.com or get in touch with any member of the society.
