A firefighter and former Royal Marine Commando from Baldock has set a new world endurance record after climbing Snowdon nine times in 48 hours.

Greg Wilson's feat - during which he carried a 40lb backpack - has helped raise money for The Firefighters Charity and The Royal Marines Charity.

Snowdon, now officially referred to as Yr Wyddfa, is the highest mountain in Wales, standing at a height of 1,085m above sea level.

Operation Snowdon Ascent took place on October 24 and 25, with Greg celebrating his 35th birthday during the endeavour.

He took the Llanberis Path, which is nine miles long and includes an ascent of 975m. Over the 48 hours, Greg travelled 81 miles and racked up a combined ascent of 8,775m - just 74m shorter than the height of Mount Everest.

By completing six ascents within the first 24 hours, Greg set a new world endurance record by breaking the previous record of five ascents. He also set a brand new record for the most ascents within 48 hours.

On each ascent, Greg travelled from the start of the path at the end of Victoria Terrace to the peak, and back again. It usually takes people around five to seven hours to complete this route, but Greg set an average pace of three hours and 45 minutes over the course of his challenge.

Fellow firefighters and veterans supported Greg at Snowdon, providing food and drink at Penceunant Isaf Café - helped by specialists GoFiit Nutrition and Steffan, the café's owner.

Greg joined Herts Fire and Rescue Service four years ago, after serving for seven years in the Royal Marines.

He has surpassed his initial fundraising target of £2,000, and is continuing to fundraise here.

The Firefighters Charity and The Royal Marines Charity help both serving and retired workers and their families with a range of resources including mental health, physical health, education, and employment support.

Greg said: “This was an immense challenge, but I really wanted to inspire my daughter about hard work and pushing your limits.

"As both a firefighter and former Royal Marine Commando I know the immense pressure and physical toll of these jobs.

"Both services are like a family with great camaraderie, but the roles are incredibly demanding and these two charities offer invaluable help to the workers.

"We were very lucky with the weather, there was a great atmosphere on the mountain with people kindly cheering each summit and I am very proud of this achievement and the money raised.”

The new record will be registered with Record Holders Republic.
