A walker reported overdue while tackling the Yorkshire Three Peaks challenge was found by rescuers late on Sunday evening.
The 46-year-old man was undertaking the 39km (24-mile) challenge on his own but failed to show up following his descent of Ingleborough.
The Clapham-based Cave Rescue Organisation was alerted at 10pm and search parties were organised, along with two search dogs. The man was found slowly making his way down Sulber Nick by rescuers, suffering from painful knees.
He was accompanied by members of the CRO, which carries out rescues on the fells and in the caves of the Yorkshire Dales, to his destination in Horton in Ribblesdale.
The team had earlier been called out after another Three Peaks walker was reported missing en route.
The CRO was alerted at 2pm on Sunday after the 52-year-old woman became separated from her husband between Pen-y-ghent and Birkwith.
She turned up in Horton soon after the rescuers arrived to carry out a preliminary search.
The CRO has responded to 34 incidents so far this year.
