Could you run 7 marathons in 7 continents in 7 days?
Doctor Andrew Murray will be doing just that, with a round-the-world marathon feat starting on November 23, just two days after he undertakes the Ice Marathon. And he's asking you to get involved - albeit a little closer to home.
"It's a genuine challenge, athletically and logistically, and a fantastic way to see some of the world in fast forward!” says Andrew.
Andrew, 32, from Aberdeen has been running for seven years and is known for running in some of the world’s most hostile and spectacular locations including the Himalayas, the Indonesian jungle, and in Genghis Khan’s hoof prints in outer Mongolia. Last year he famously ran 2,660 miles from Scotland to the Sahara and this year won the North Pole Marathon.
Andrew will travel economy class 41,000kms around the world, will burn 6,500 calories a day - enough for a 600kg crocodile - go through seven pairs of socks, run on glaciers, through deserts and mountains and past iconic landmarks such as the Pyramids, all in just seven days.
"Running an ultra marathon every day for a week is incredible enough without having to contend with a huge dollop of jet lag and a temperature range of between -25 and +35 celsius!” says record-breaking long-distance cyclist Mark Beaumont.
Andrew hopes to raise £10,000 for the Scottish Association for Mental Health and raise awareness of the benefits of physical activity on mental health.
To support him in a more feasible way, you can join up for free to www.5x50.co.uk to walk, run or cycle 5kms each day for the week he is away. Competitors who enter the daily mini challenge will be entered into a prize draw to win items such as signed Chris Hoy T-shirts and Scotland Rugby goodies, as well as luxury getaways at the iconic Balmoral Hotel in Edinburgh.
