Andy Murray may have become the first Briton to win Wimbledon since 1977, but his finest achievement may soon pale in comparison to that of his brother-in-law’s.
Lieutenant Scott Sears is attempting to become the youngest person to solo travel to the South Pole.
The 27-year-old – the younger brother of Kim Sears, who married Murray in 2015 – is hoping to complete the 702-mile trek in time for Christmas Day.
If successful, Sears would break the record by two years.
“When I told my mother she was horrified, but after that initial shock she was obviously very supportive,” he said.
“She is eternally suffering because of me, I thought I managed to annoy her the most I possibly could when I joined the infantry and then I chuck this on her as well.”
He flies out to Chile on Wednesday, before heading to Antarctica’s Hercules Inlet to commence his unassisted adventure.
An ominous task awaits him: temperatures as low as -60°C and 100mph winds.
He will haul a 100kg sledge, packed with his equipment and food, as he survives on a diet of “quite tasty” dehydrated meals during his near-50-day mission.
“I am very excited – it has been two years in the planning so it is nice to finally be under way,” he added.
“I’m looking forward to the moment where I finally get chucked out the side of the plane and I am actually there looking out at the expanse of Antarctica after years of visualising it and dreaming of it.”
Sears has already raised over £25,000 for the Gurkha Welfare Trust to help rebuild schools in Gorkha, Nepal, which were destroyed in the 2015 earthquake.
