Athletes are being offered the chance to put their stamina to the test surrounded by some of the region's most beautiful countryside while raising funds to help save lives.
Organised by Northumbrian Water's Commercial Contracts Manager and Run Peterlee founder, David Ferguson, the Derwent Reservoir Trail Races is on June 2 and features two races: a seven-mile trail race around the multi-purpose track of the beautiful Derwent Reservoir, and a three-mile run that takes in an equally stunning route.
All proceeds from the event will go towards Northumbrian Water's international charity partner WaterAid, which aims to create a world where everyone has access to safe water and sanitation.
David said: "Now in its third year, the event is starting to grow in reputation and we're on track to fill all of the 200 places available.
Andrew Blakemore, Northumbrian WaterAid Chairman, added "More than 844 million people don't have clean water close to home – we're extremely lucky in the North East to have access to safe water and sanitation but the reality is that most of us take them for granted.
"The location of the Derwent reservoir races has been specifically chosen to emphasise this, running alongside 11, 000 million gallons of water.
The three mile race starts at 9am at the reservoir dam and heads towards Pow Hill Visitors Centre, past South Shore before turning at Pow Hill Visitor's Centre at which point participants run back toward the dam.
The seven mile Trail Race starts at 10am, also at the dam. It follows the same route, but continues on past Cronkley Bay, Henry's Plantation and The Meadow towards Millshield Picnic Area, before racers turn one more time and head back to the finish at the dam.
