Fell running and chuff

Murray had some classic symptoms of acute mountain sickness, with fluid starting to collect in her brain.
She was given oxygen, steroids, and placed in a portable hyperbaric pressure chamber, also known as a Gamow Bag, where she spent the night with a worried boyfriend Jamie in a sleeping bag alongside her.
Every five minutes a porter would blow more air into the chamber to keep it at the right pressure.
"There was a small window in the bag so I could see Jamie and we could shout at each other through it," Murray recalled. "But it was a pretty miserable experience."
The next morning she was helped down the valley a little way, and made a rapid recovery as her blood oxygen level returned to something approaching normal.
Remarkably she completed the marathon a week later, in under eight hours.
Fellow Scot Angela Mudge, a sports masseuse who lives near Stirling and is a member of the Carnethy Hill Running Club in Edinburgh, had no such problems.
The 37-year-old, originally from Tavistock in Devon, is a world champion in sky running, a form of fell running in mountainous areas such as the Pyrenees and the Dolomites.
She is now the new women's record holder for the Everest Marathon, having covered the course in five hours and three minutes, beating the previous record of former Macclesfield Harrier Anne Stentiford, whose 5 hrs 16 mins had stood since 1997.
"I had absolutely no idea what to expect," Mudge said.
"I race all around the world but have done nothing to compare with this.

"It is the toughest marathon you are ever going to do, and I just wanted to do it once. I always wanted to visit Nepal, and I love using my running to see places."
Mudge finished eighth overall, the first woman home, and the second 'Westerner'.
The first, much to his surprise, was Craig Mattocks, a 34-year-old building surveyor from Northampton, where he is a member of the Wootton Road Runners Club.
"I'm chuffed to bits, I was just hoping for something under six hours," he said, having covered the course in 4 hrs 53 mins to finish fifth.
"I do quite a lot of road running, and did some fell races in preparation for this. But I really just wanted to come to the Himalaya and enjoy the scenery."
