A group of challenge walkers who got lost attempting the Yorkshire Three Peaks had only one headtorch between the four of them.

Rescuers said the three women and a man had no map and compass.

The Clapham-based Cave Rescue Organisation was called out about 8.40pm on Sunday after the group got lost while descending Ingleborough towards Horton in Ribblesdale.

A team spokesperson said: “While trying to establish their location, a small party of team members set off from Horton to check the area leading back to Sulber Nick.

“Eventually contact with the group was established, and a GPS location on The Allotment was confirmed using Sarloc. Team members from Clapham collected the group and escorted them down, while the other team members were stood down.”

Sarloc is software developed by former Ogwen Valley Mountain Rescue Organisation member Russ Hore that is used to send a link to the casualty’s smartphone which, when clicked, uses the phone’s inbuilt GPS receiver to pinpoint their position and send this to rescuers.
