A daredevil grandmother who has performed extreme stunts for charity is going on a trek abroad.

Olive Sorrill, 74, from Banstead, is going on a 9km trek to Everest Base camp, at 5,150m of altitude, to raise funds for St Raphael’s Hospice in North Cheam.

Last year, the mother-of-four and grandmother-of-five was the brave passenger of a small Cessna plane which did loops, death spirals, flew upside down and even turned its engine off for a brief moment.

Mrs Sorrill said: “The aerobatics was fantastic. It was absolutely brilliant.

"This time we’re going to Tibet and doing this 9km-trek to the Base camp.

"When I first heard about it I thought ‘9km, it’s about 5 miles, so it should be easy’, but it is at some altitude, so should take a little bit more effort."

According to Mrs Sorrill, her addiction to extreme stunts started when her daughters gave her a ride in an F1 car, at Brands-Hatch, when she was 60.

Since then, she did paragliding in Mexico, Harley-Davidson riding in Australia and a parachute jump a couple of years ago, for charity, to name but a few.

She said: “Next year, when I turn 75, I’m planning to throw a big party for all the family and I’m going to include all of these crazy things on my birthday invitation.”

But the daredevil pensioner is not thinking about retiring yet, and also dreams about doing wing walking and descending on a zip wire at Epsom Racecourse in the future.

Last year, she raised over £2,000 to St Raphael’s Hospice and is hoping to raise even more this year.

Mrs Sorrill said: “The care people get when they go into the hospice is fantastic.

"It’s a fantastic atmosphere in there and they should be able to continue offering that to patients.”
