A WALKER who suffered a broken leg and another who suffered a seizure, both while attempting the Yorkshire Three Peaks Challenge, have been airlifted to hospital.

Volunteers from the Yorkshire Dales Cave Rescue Organisation were called to the 694m Pen-y-Ghent at 8.05am on Saturday by Yorkshire Ambulance Service, to reports of a hiker who had suffered a seizure and lost consciousness while ascending the mountain.

It is understood the walker had begun the 24-mile walk, which involves climbing the three tallest mountains of Yorkshire within 12 hours, shortly before.

Rescuers helped Yorkshire Air Ambulance staff to get the casualty into a helicopter before the patient was transferred to a road ambulance at Dale Head.

Just as team members were packing up, the rescuers received a call to another Three Peaks walker, a 41-year-old woman who had sustained a lower leg fracture at High Birkwith, between Pen-y-Ghent and the national park's highest peak, Whernside.

On arrival at the scene, rescuers called for the Yorkshire Air Ambulance due to the severe nature of the injury.

The casualty was treated and packaged for transport, and carried by stretcher to a helicopter, before being transferred to hospital.

The British Heart Foundation was among a number of organisations running challenges over the peaks on Saturday, to raise funds for research.
