An extreme adventurer has been recognised by Prime Minister Theresa May for his efforts in promoting the benefits of health and exercise.

Mrs May honoured Dr Andrew Murray with a Points of Light volunteering award for his extreme challenges in promoting health and exercise.

Dr Murray, from Aberdeen, has raised more than £170,000 in running challenges for the Scottish Association for Mental Health, the African Palliative Care Association UK and Yamaa Trust.

He has completed several extreme fundraising runs. They include the North Pole Marathon, seven ultra-marathons on seven continents within seven days, a 4,300km run from John O'Groats to the Sahara Desert and the first Genghis Khan Ice Marathon in Outer Mongolia.

A doctor for the University of Edinburgh, the European Tour Golf, the SportScotland Institute of Sport, Scottish Rugby, and Merrell UK, he also provided voluntary medical services in Kenya, Outer Mongolia and Namibia.

The Points of Light award recognises outstanding individual volunteers and people who are inspiring others.

In a personal letter to Dr Murray, Mrs May paid tribute to his efforts.

She said: "Your remarkable running challenges are raising funds for three important charities, but also inspiring countless people to become more active and improve their health."
