Britannia Building Society has raised over £400,000 for the Alzheimer's Society.
It came after the building society's best ever charity fundraising year and it teamed up with Alzheimer's Society, which is celebrating its 30th birthday this year.
As part of the fundraising, Britannia's Peter Mansfield ran one mile at each of the 13 football clubs the organisation has a partnership with, including Arsenal.
"Alzheimer's Society is thrilled with the success of our partnership with Britannia. We have enjoyed reading about all the fun activities that have taken place across the country," said Neil Hunt, chief executive of the charity.
The money raised by Britannia will go towards fund care and support services and will make a difference to the lives of those affected by dementia, he added.
Last month, the easyJet and Alzheimer's Society charity partnership was launched.
David Van Day was on hand to serve tea to easyJet cabin crew and staff in support of the charity.
