For reasons best know only to myself, at the age of 50, I have decided to run a marathon.

I’m not a natural runner and at over 90kg I’m more adept at pushing weights in the gym and doing circuits rather than running 26.2 miles (42.2km) and the furthest I have ever run as part of an organised event is 10km.

My place isn’t a charity place and I have paid for my entry myself, but I would like to raise for charity.

For personal reasons I have chosen 3 charities to benefit from my stupidity.

Having seen first hand how cruel the illness is and how much the support the patients and families need; one of my chosen charities is Alzheimer's Society.
