One in three of us born in the UK today will develop dementia in our lifetimes. Its the biggest health and social care challenge we face. We vow to help end the devastation caused by dementia, but we cant do it without you.

Together we are help and hope for everyone living with dementia.

We're challenging you to cycle between 100 and 500 miles in 30 days. Sign up, track your miles and raise vital funds to help us support people living with dementia. If you raise £100 you'll receive a medal as a special thank you for your support. Raise £300 and you'll earn your own Alzheimer's Society cycling jersey.
