Stephen's London to Brighton 100k
Until I got involved I never realised Age UK offer so many different and varying services for elderly people, including HandyMan services, Meals and Drop-in Centres where people can just be social.
There are almost 2 million older people in the UK who suffer with loneliness, and I hope the funds I raise will help Age UK Medway [Kent Rivers] reach out to more of them and help remind them how great life can be!

"Whether it is the incredible Action Challenge staff and helpers you find along the way, or whether you are lucky enough to find a walking buddy, you will never feel alone, and at no stage will you meet anyone who isn't willing you to do the very best you can. With determination, and mutual encouragement from my walking buddy, I made it to the finish line and to my fantastic waiting support crew."
