The 30-year-old aims to make as many headlines across the world as his tennis namesake by running more than 30 miles a day from John O’Groats to the Sahara desert in North Africa.
The gruelling charity challenge, which begins on November 8, will see the Aberdeen GP complete eight miles MORE than a marathon every day for nearly three months.
Japan’s Akinori Kusuda, 65, ran the 26.2-mile distance 52 days in a row last year to claim the Guinness World Record for the most marathons run on consecutive days.
But if Andy achieves his amazing feat the world record will be his.
He said: “It would be amazing to be the benchmark for marathon running. I’m not at that stage yet though so I need to keep focused on getting the job done.”
Andy admits his Scotland-to-Sahara adventure is the biggest challenge of his life and his preparations are as brutal as the journey that awaits him.
He plans to run a whopping 100 miles every week until the day his expedition begins.
He is fitting in a night each at his local tennis and squash clubs and two games of five-a-side with his friends to toughen-up his training schedule.
Last weekend, he shattered the record for running the length of Hadrian’s Wall by finishing the 84-mile stretch in 16 hours and 59 minutes – THREE HOURS faster than previous holder Jon Watts.
This Saturday, he is tackling Skye’s spectacular Cuillin Ridge, a range of mountains regarded as one of the UK’s most daunting.
Andy said: “I’m so tired at the moment from all the training. And I know that by December I’ll feel twice as exhausted.
“I’m not complaining though. The best thing you can do is forget about what you’re doing.
“When I’m running or taking part in any sport, I lose all my thoughts. I’m determined to push myself to the max for this.”
John O’Groats to Sahara Desert
DETERMINED Andy starts his epic journey at John O’Groats on November 8.
He’ll head south after stopping off to climb Ben Nevis on day five.
Then he will pass through England, France and Spain before enduring temperatures of up to 45°C (113°F) in the Sahara. The adventure finishes in Merzouga, Morocco on January 27.
Andy said: “In Spain and Morocco I’ll have to run with a SLEDGE because of the sand.
“It will carry my food, juice, waterproofs, Vaseline, painkillers, passport and money. It’ll be tough, but there’s just no way round it.”
Andy has been taking running tips from marathon man Mark Cooper, 27.
The pair teamed up for the Hadrian’s Wall run on Saturday.
Edinburgh office worker Mark ran 50 marathons in 56 days – 1,310 miles from Holland to Spain – earlier this year.
