ADVENTURER and farmer Chris Brown is planning to head to Everest to run the world's toughest and highest marathon at the age of 73.

He has done it before but that was 30 years ago and Chris, from Baldersby near Thirsk, is just hoping he has the stamina to do it again.

Chris is renowned in the region for his climbing exploits having scaled the highest mountains of all seven continents as well as running the desert marathon des Sables.

He’s raised tens of thousands of pounds to help charities which work with sufferers of schizophrenia, particularly the Claro Enterprise Workshops in Harrogate, and has been awarded the MBE.

Now he wants to redo the marathon as a tribute to the people of Nepal and to support the fundraising efforts of mountaineer and friend Doug Scott. The race sets off from Everest base camp and goes down to the Sherpa town of Namche Bazaar.

Chris is planning to finish the marathon in around nine hours. Last time it took him six hours 20 minutes

“I was a three-hour road marathoner back then," he said. "Going back to do the race now is my way of giving something back. If my example can persuade others to have a go, then we will be able to help the Nepali people all the more."
