A 70-YEAR-OLD Supergran has successfully climbed the highest mountain in Britain.

Pam Clemm, of Lynwood Grove, Moredon, made it to the summit of Ben Nevis in four hours 20 minutes – and even managed a sprint down part of the mountain on the way back.

She celebrated her achievement, done to mark her 70th birthday, with a celebratory pint of Guinness at the foot of the mountain.

Pam, who is jokingly nicknamed Supergran, is planning her next sporting feat, a possible trip up Mount Snowdon or even the Three Peaks Challenge, climbing three mountains in three days.

Pam has also cycled 100 miles in one day and all her efforts are to raise money for an electric wheelchair for her nine-year-old grandson, Paul, who has cerebral palsy.

She also wants to fulfil her late husband Victor’s last wishes that she take care of their grandson.

Pam said looking out on the view holding a St George’s flag was a proud moment.

“It was absolutely wonderful, I can’t believe it,” she said.

“I loved every minute of it and it was a big achievement for me, something special.

“I didn’t have to be carried or crawl, I did it on my own. I’ll never forget this birthday.”

She said she did not really suffer at all during the 4,406ft ascent and was encouraged by Nathan to run down the smooth parts of the route on the way back.

She said: “It felt a bit like The Sound of Music, running down the mountain so that was really lovely.”

She puts her fitness down to two weeks of intensive training running up and down Cheril Hill, near Calne.

However, Pam has come a long way since the death of her railway worker husband Vic, 75, in August 2004, which resulted in her becoming overweight.

Pam’s situation was not helped when, two years ago, she suddenly lost most of her hearing.

She took drastic action last year and starting boxing, running and cycling to lose four stone and slim down from a size 24 to a size 14.

“It just shows you what you can do if you believe you can do it,” said Pam.

“I was determined to get to the top and I did.

“It’s like a new life for me, I have achieved so much.

“People said to me I think Victor would be really proud of you and I think he would be.

Pam hopes her efforts will help raise £500 of the £2,000 Paul needs to get the freedom-giving wheelchair.

She said: “It was a lovely day and you had a beautiful view and to think I climbed up there and I had done it for my family, it was really something special.”

Pam’s friend and training partner, endurance athlete Nathan Taylor, who accompanied her up the peak, was not surprised by Pam’s achievement.

He said: “Perhaps Pam exceeded her own expectations, but not mine.

“She’s worked really hard. There’s no doubt she’ll break world records in future.”
