The woman was walking between Pen-y-ghent and Ribblehead
A walker tackling a challenge route was rescued after injuring herself when she slipped.
The Clapham-based Cave Rescue Organisation was called out about 10.20am on Saturday to aid the walker who was attempting the Yorkshire Three Peaks.
The 33-year-old slipped on wet, muddy grass near High Birkwith, between Pen-y-ghent and Ribblehead, and injured her ankle.
A team spokesperson said: “Having given her pain relief and applied a splint, team members carried her by stretcher to a waiting road ambulance.”
It was the CRO volunteers’ 56th callout of the year.
