Adam Keen, 26, from Worthing, West Sussex is taking on a 244 mile bike ride for the Royal Air Force Benevolent Fund in memory of SAC Ryan Tomlin. Adam tells us more in this blog.
Ryan Tomlin was just 21 when he was killed serving with the RAF Regiment in Afghanistan this year.
It is tragedies like this that bring home how real the war is. I wanted to do this bike ride in honour of my friends in Afghanistan, who are doing everything they can to protect us.
This is why I am cycling one mile for each day that Ryan's squadron, 2 Squadron of the RAF Regiment, is on operations in Afghanistan. The ride is 244 miles and I am cycling from Worthing everyday, doing about a 35 mile round trip in different directions.
All the money I raise will be going to the Royal Air Force Benevolent Fund. I would like to really give this great charity as much as I can as they are there for the Royal Air Force now and in the future.
Just yesterday I dropped in at Princess Marina House (PMH), the RAF Benevolent Fund's break centre in Rustington, where I met the general manager, Shirley Steeples.
They do great work there, offering respite breaks for anyone who has ever served in the RAF family, including those affected by dementia. Visiting there really illustrates how the charity is at the heart of the RAF family.
So if you can dig deep and make a contribution to my ride you'll be helping all our RAF heroes in Afghanistan and elsewhere, who are doing so much in defence of our freedom.
Remember - it does not matter how much you give, it will all count.
