Hundreds of runners will be tackling a gruelling race which takes in picturesque coastline scenery this weekend.
The third annual Durham Coast Half Marathon will get under way this Sunday.
Organisers describe it as a challenging and scenic route which is not for the fainthearted.
The race will get under way at Nose’s Point in Seaham and follows the East Durham coast all the way to Crimdon Dene.
Officials have hailed the race as “a great way for energetic types to experience the stunning Durham Coast.”
The 13-mile route is full of descents and climbs and runners will also face around 300 steps along the way.
Spectators are being invited to support the runners by turning up at the start and finish lines, as well as supporting the competitors all along the course.
The event has been organised by the National Trust and starts at 11am in Seaham.
The race begins at Nose’s Point and free car parking is available at the Spectrum Business Park, which is around five minutes walk from the start area.
Entries to the race are now closed and organisers say around 300 runners are expected to tackle the course.
The Hartlepool Mail wants runners and their supporters to send us photos of their momentous day of racing. Tell us your story and how the race went for you.

Alternatively, people can also tweet them to @hpoolmail or post their photographs to the Hartlepool Mail on Facebook.
For those who want to enjoy the coastline at a more leisurely pace, guided walks are also taking place along the coastline.
The next is a seven-mile stroll costing £3. It will be held on Tuesday, June 16, and will start at 10am outside The Stapleton Arms, in Hawthorn Village.
It is described as a stroll and a chat with a Ranger.
It is a chance to learn about the natural and human history that gives the area around Hawthorn Dene its special character.
Children are welcome and so are dogs on leads.
