Every penny raised makes a real impact to people and places in neighbourhoods and communities across the UK.

£350

will pay for ten homes to receive winter warmer packs through our Green Doctor energy efficiency programme, keeping vulnerable people warm in the colder months.

£500

will sponsor two families to take part in an eight-week Wellies in the Woods course, inspiring a love of nature in young children and families who do not have good access to green spaces.

£1,500

will set up a veg box or community fridge at a Green Community Hub in an area lacking provisions, so people can reap the benefits of both growing and eating soil to table produce.

By joining Team Groundwork, we will be with you every step of the way.

The support I got leading up to the event, and on the day, was fantastic. The team cheering me on really kept me motivated. I had perfect conditions for running through some of London’s best parks and seeing so many iconic landmarks.
