Three women have completed a challenging summits run to raise funds for a mountain emergency service.
Jenny Allen, Jamie Aarons and Alex Berry ran 64 miles and climbed 16,886ft to reach 19 “trig” pillars in the area covered by Lomond Mountain Rescue Team.
They completed the gruelling feat in an impressive 22 hours and 45 minutes.
The friends, from Glasgow and Stirlingshire, started at Maol Mor trig in the Trossachs at 11am on April 6 and finished on the summit of Ben Lomond at 9.45pm the next day.
So far the trio has collected almost £3,000 through donations and sponsorship.
After the run, Jamie, of Carbeth, Stirlingshire, said: “The weather turned out to be an unpleasant surprise, much colder, windier and wetter than forecast.
“But the challenge was far more fun than I had anticipated and the time absolutely flew by.
“We made a great team and we are delighted to have raised so much money for Lomond Mountain Rescue Team.”
The trigs are a shortened word for triangulation points. They were positioned across the UK in the early 20th Century as a way to map the lie of the land.
Today’s OS maps are based on this original mapping system.
