A family and their supporters are scaling the heights to raise awareness of a rare disease.

And they are hoping to break a world record in the process.

Sam Booth is aiming to get 200 volunteers together to scale a mountain – in Brighouse – and go down in history.

Sam is organising an event never before attempted.

He hopes to climb the equivalent of Olympic Mons on Mars (the highest mountain in the solar system) at the Rokt Climbing Gym, Brighouse. The climb will take place over 25 hours on the weekend of April 26 and 27.

The 25km totally vertical climb will involve 1,191 ascents of the lead wall at Rokt. Already around 100 people have registered an interest and Sam is hoping to double that number to spread the load.

He is currently in discussions with the Guinness Book of World Records regarding the criteria for a world record attempt.

Sam is organising the event through the B. Baggins Foundation for Limb Girdle Muscular Dystrophy (LGMD).

Sam set up the charity in 2012, along with his aunt Beverley Swales, shortly after his brother Ben, 21, was diagnosed with the rare debilitating disease. Ben, of Chestnut Meadows, Mirfield, had been an active rugby-playing teenager and fitness enthusiast.

But three years ago, he began to struggle walking up hills. He is currently studying for a Master’s degree in electronic and electrical engineering, but finds simple physical tasks like walking upstairs, cleaning his teeth or shaving difficult and exhausting.

Sam said: “We are hoping not just to raise funds, but also to raise awareness of LGMD.

“We are the only registered UK charity which specifically supports this rare and currently incurable group of diseases.

“We are hoping to get 200 people together for the climb.

“It is suitable for all ages and abilities and there will be three qualified supervisors from Rokt there at all times round the clock.

“No-one has done it before, it will be a fantastic achievement for every person taking part.”

Over the last two years B. Baggins has organised a number of family-friendly events in aid of LGMD, including a cartoon snail race, barn dance, summer fair and various sporting events.

Anyone interested in participating should contact the charity online at www.bbaggins.org or on Facebook at B. Baggins Foundation for Limb-Girdle Muscular Dystrophy:

Limb-girdle muscular dystrophy (or Erb’s muscular dystrophy) encompasses a large number of rare disorders. The muscles most severely affected are generally those in the hips and shoulders and there is currently no cure and the disease worsens over time.

Sufferers generally have difficulty walking, going up and down stairs and rising from a chair. Regular falls are common due to weak leg muscles. Some sufferers eventually lose all mobility.
