Durham Coast half marathon

Runners at the start of the half marathon

This year's race takes place on Sunday 28 June, with hardy contenders following a scenic and challenging 13.1 mile route along the coast from Seaham to Crimdon Dene.

A serious test for even the toughest of athletes, the Durham Coast half marathon has become notorious for a series of ascents and descents featuring steep flights of steps. It is a regular fixture in the calendar of many participants. 

" We’ve seen the race grow a lot since its first year in 2013, people really seem to love it. Even those who swear ‘never again’ at the finish line often come back to take on those steps again. "
- Wayne Appleton, ranger on the Durham Coast

Runners who'd like to become a next-level fundraising champion can mark the National Trust's 125th anniversary in 2020 by joining our 125 challenge to raise extra funds to look after the landscape and wildlife of the Durham Coast. Simply email sports@nationaltrust.org.uk for your fundraising pack and free running vest.

To lend support on the day cheering the runners on, you'll find the best view points at the start and finish lines as well as Cotsford Fields near Lime Kiln Gill car park in Horden, Hawthorn Dene, Castle Eden Dene mouth plus footpaths near Easington Colliery, Blackhall Colliery and Blackhall Rocks.

It takes a large team working together to make this event happen. Anyone who isn’t a runner but would like to get involved can sign up to be a volunteer marshal. It’s fun, a good way to meet new people and you don’t need any experience. For more information, please send us an email

It’s great to see familiar faces returning to the Durham Coast each year. For some people, entering their first race here is also their first visit to this stunning part of the coast. Happily, many go on to bring their families back to visit another time.
