Vida’s employees at all levels will take part in a variety of activities, such as a 2.6-mile sky dive and a mixed marathon relay. Chief executive Anth Mooney will also walk his dog Walter in a half marathon.
This is the second fundraising event the lender has arranged for Crisis since partnering last year.
Vida pledged to donate at least £150,000 to Crisis over a three-year period.
Mooney said the alternative marathon was inspired by the London Marathon, which the lender wanted to replicate in “some small way with a twist”.
He added: “The aim was to bring people together after a tough 18 months in support of our charity partner Crisis in a way that is open to everyone regardless of interests, ability or location.
“At Vida we believe no-one should be forced into homelessness. I’m grateful to all my colleagues who are taking part, or supporting, our first alternative marathon. I know I speak for everyone at Vida when I say we are delighted to be partnered with Crisis to assist the fantastic work they do to change people’s lives for the better.”
Richard Lee, head of fundraising at Crisis, said: “We are so pleased to be working with Vida and support their efforts in raising vital funds with the alternative marathon.
“The past year has been incredibly tough for everyone and having somewhere safe and secure to call home has never been more important. With Vida’s help, we can support people and help them find a path out of homelessness for good.”
