Former Borders doctor Andrew Murray and fellow Scottish International distance runner Donnie Campbell ran Scotland’s 10 highest mountains in 13 hours and 10 minutes earlier this month.
The self-set challenge of completing The Big 10 in under 24 hours saw the pair leave home at 4.20am to drive to the Nevis range to climb Ben Nevis and others . They finished on Cairntoul in the Cairngorms at 5.30pm.
The pair, who were followed by BBC Scotland’s The Adventure Show, ran for nine hours and 10 minutes, with the rest of the time spent driving.
Now Edinburgh-based, Dr Murray, 34, a GP and sports medicine doctor, said: “The Big 10 had it all in terms of spectacular ridgelines, some wildlife and highly variable weather.
“We had fog, wind, rain, and even a glimpse of sunshine. We were both glad the promised thunderstorms did not materialize.
“For me, definitely, the toughest part of the day was dealing with the wind, rain and low visibility in the Cairngorms, when we were already tired. Part of what we were looking to do is draw attention to the benefits of getting regular exercise in the great outdoors.
“It really gets the happy hormones going, and helps prevent and treat over 40 major health problems.
“Even walking 30 minutes five days a week increases your life expectancy by more than seven years”
