Aberdeen GP Dr Andrew Murray beat 41 other runners from around the world to complete the UVU marathon in 4 hours 17 minutes.
The event took place on 6 April across the frozen Arctic ocean in temperatures of -26C.
Dr Murray said: ‘Running at the North Pole is an experience of a lifetime. Your feet sink into the snow with every step and you need to protect yourself from the cold. But it’s worth it, the landscape is amazing, and it was fantastic to see every single runner finish.’
Dr Murray is currently seconded to the Scottish government as their physical activity champion - promoting the value of getting active for health.
He said: ‘The message to get active is so important, we are taking it to the ends of the earth. I’d urge everyone to do a bit more walking, or whatever form of physical activity suits them - everything counts. Keep doing the walking, gardening or sport you are already doing and try to build a little more into your life.’
In 2010 Dr Murray ran from John O’Groats to the Sahara desert to raise money from Scottish charity the Yamaa Trust.
