RUNNERS who love a challenge have been invited to sign up for the National Trust Durham Coast Half Marathon.

The 13.1 mile route along the Durham Heritage Coast, from Seaham to Crimdon Dene, on Sunday June 16, is entirely off-road.

It takes in a combination of gentle sections along cliff top paths, as well as steep ascents and descents, including approximately 320 steps – a tough test, even for seasoned runners.

The National Trust is an independent conservation charity and all profits from the race go directly to fund work caring for the local coast and countryside.

National Trust ranger and event organiser Wayne Appleton said: "We’re now in the seventh year of this event and it seems to keep growing in popularity.

"I think it’s the beautiful coastline that brings people back year after year, even if they swear ‘never again’ after tackling all the steps! The fantastic atmosphere and cake at the finish line definitely help too. It’s great that so many people are learning what an amazing place the Durham coast is to visit and how we’re working to look after it.’

The route will be clearly marked, with regular water stations to keep runners hydrated. Volunteer marshals are key to ensuring the event runs smoothly.

Mr Appleton added: "We wouldn’t be able to hold this event or carry out all the work we do on the coast without the help of volunteers.

"They do a brilliant job and have so much enthusiasm. Anyone who’d like to get involved can sign up as a volunteer marshal. It’s fun, a good way to meet new people and you don’t need any experience."

All runners will receive a t-shirt and medal as well as free refreshments at the finish line. Prizes will be awarded to the first three men and women, as well as winners in each age category.

Entry to the race is £28 per person and includes minibus transfer from the finish back to Nose’s Point.
