The Derwent is a mountain river. From its source at Sprinkling Tarn it gathers all the rain and water running off the north-western fells. It’s home to otters, atlantic salmon and vendace – the UK’s rarest freshwater fish. But with increasing pressure from pollution and severe floods we must take action now.

Help our supported charity the National Trust ‘slow the flow’ of water from summit to sea to protect this beautiful lake district river, the mountains and valleys it flows through, the wildlife and people that depend on it.

The mountains around Keswick are the Derwent’s ‘river lands’. All the money you raise will help the Riverlands project to improve the health of the mountain river Derwent.

Sign up to fundraise for our supported charity The National Trust when you book your place on a Keswick Mountain Festival sporting event, you’ll receive a fundraising pack and a limited edition running vest.

The National Trust is an independent registered charity, no. 205846 and receives no core funding from government
