I’ve no idea why I decided to pick the challenge of sitting on a rowing machine until I've completed a marathon (42195 metres or in old money 26 miles and 385 yards).

However, I do know that I am doing it as my dad Harry has vascular dementia. Physically he has diminished, his understanding of everyday tasks has reduced and he needs constant care provided by a nursing home. We are lucky though as he still knows who we are and occasionally can still be quick witted.

Nearly everyone can tell a similar story about friends or family who have suffered with either Alzheimer’s or Dementia so I thought the least I could do was try and raise some money to help this charity and also put some towards research.

I realise that this is a stupid time of year to ask for donations but appreciate anything you can give to help me reach my target. Thank you.
