- Watch a report by ITV News Anglia's Russell Hookey.
A man with early onset dementia is cycling across four counties on his penny farthing to raise awareness of the condition.
Peter Berry from Friston will take six days to travel through Suffolk, Cambridgeshire, Lincolnshire and Norfolk, a journey of 300 miles.
Sadly he is likely to remember little or nothing of the trip.
Peter is raising money for Young Dementia UK and is being escorted by friends.
He was diagnosed with Alzheimer's at the age of 50. He was running the family firm, a timber saw milling business, when the first symptoms appeared after a series of mistakes at work.
Peter who is currently taking part in a Channel 4 programme 'The Restaurant that makes mistakes', says he want to show that people can live well with dementia.
Peter currently has a blog in which he shares his experiences of living with dementia.
