A Hampshire-based charity is aiming to raise £20,000 in one week.

Cardiac Rehab, in Alton, is taking part in the Big Give Christmas Challenge between December 3 and 10.

The charity, which supports people with heart problems, will be able to double every £1 donated during this match-funded campaign, with help from the Hampshire Cricket Foundation and other donors.

The money raised will help Cardiac Rehab provide specialist exercise services and maintain its exercise centre in Chawton Park Road.

To coincide with the fundraising event, the charity has released a short film called Taking Fitness To Heart, which showcases its services.

Sarah Quarterman, CEO of Cardiac Rehab, said: "Our new film enables us to explain to supporters and potential new exercisers who we are and what we do, in a very concise and clear way.

"During the Big Give Christmas Challenge, which is the UK’s biggest match-funded campaign, there will be an opportunity for your donation to be doubled.

"And we very much hope to achieve our target of £20,000, through the generosity of our community and individual donors and through Gift Aid by individuals."

The Big Give Christmas Challenge supported more than 1,000 charities last year, raising £33 million in one week.
