An RAF Waddington airman plans to walk from Lincolnshire to London over four days, carrying everything he needs on his back.
Cpl Ray Casson will stop at campsites overnight so will need to carry his clothes, sleeping bag, rations and a shelter sheet to sleep under with him as he tackles the 140-mile challenge in aid of the RAF Benevolent Fund, the RAF's leading welfare charity.
The 31-year-old father also plans to carry a poppy wreath with him to lay at the Bomber Command Memorial in Green Park in London. It currently lies in the Airman's Chapel in Lincoln Cathedral and Ray will collect it before embarking on his journey at 12noon on Tuesday, September 29.
Ray said: "I have been running and walking with a Bergen on my back to get ready for the trip. I got to Waddington in March and I saw how much the Fund does for personnel here. I have seen some of the work which goes on and it speaks volumes.
"Earlier this year I met a veteran injured in Afghanistan who the Fund had helped and the support the Fund has given him is amazing. Also, my kids go to the Airplay youth club so they benefit too.
"I am a big believer in looking after your own, the RAF looking after the RAF."
Not one to make life easy for himself, Ray plans to wear his combat boots and 'green' uniform during the challenge. He hopes to arrive in London at around midday on October 3. But he's not resting on his laurels, the following day he will take part in Bear Grylls' Ultimate Survivor race in Trent Park – a 30km obstacle race with 'surprise' challenges.
Ray is no stranger to extreme fundraising. In June of this year he completed a 75km obstacle race, Airfield Anarchy, completing the course several times to reach the distance, all while dressed in full body armour. His efforts raised £1,300 for the RAF Benevolent Fund.
This time, Ray hopes to raise £500 for the Fund. You can sponsor him at www.justgiving.com/Raymond-Casson3
Simon Footer, RAF Benevolent Fund regional director, said: "I am continually impressed by the lengths our fundraisers will go to support the Fund and Ray is no exception. His determination to make this challenge as difficult as possible for himself is testament to his commitment to raise as much as he can for the charity.
"The RAF Benevolent Fund receives no government funding and without the support of generous fundraisers like Ray we simply would not be able to offer the financial, emotional and practical support to the RAF Family which we do."
