GP Andrew Murray to run seven world ultra marathons
A GP is to run seven ultra marathons on seven continents in seven days in an attempt to promote health and raise more than £10,000 for charity.
Andrew Murray, who is from Aberdeen and now lives in Edinburgh, was recruited by the Scottish government to highlight the importance of physical activity.
His challenge will take him to Antarctica, Patagonia, Atlanta, London, Egypt, Dubai and Australia.
He hopes people will walk, run or cycle 5km each day he is away.
The GP, whose will begin his attempt on 23 November, said: "It's a genuine challenge, athletically and logistically.
"But the most important thing is to raise awareness of the benefits of exercise - being active regularly is the single best thing for your health.
"If we get 6,000 people to walk or run 5km a day for a week, that's enough to go around the world five times."
Dr Murray will also be raising money for the Scottish Association for Mental Health.
Last year he ran 2,659 miles - averaging more than 34 miles a day - from Scotland to the Sahara in 77 days.
