Starting from the seaside town of Newcastle in County Down, you’ll hike the 7 highest peaks in the Mountains of Mourne. Your circuit means you finish your day right back where you started, at sea level.
This is a long, tough and exhilarating day in the hills. You’ll cover over 18 miles, with 2,500m of vertical ascent. With the right training behind you, you’ll be able to confidently navigate through the very heart of our stunning Mourne Mountains.
Electronic timing and radio-linked tech will track you over each summit and col throughout the day. The hills are steep, but the craic is ninety, and the encouragement of our volunteer marshals is legendary.
The Original Mourne Seven Sevens promises a warm welcome, unrivalled care and the chance to be part of something truly special. We are so proud of our Event Team, all volunteers, who love the outdoors and are looking forward to delivering another fabulous event this summer.
Join us on 9th August 2025 to earn your Finishers Certificate, much coveted 7x7s badge, and your place in history.
Our History
Back in 1992 the Spartan Red Sox hosted the very first “Seven Sevens”, with just 15 participants. At the time it was popularly believed that there were 7 mountains over 700m in height and whilst that was corrected in later years by Ordnance Survey, the name had stuck. Popularity in in the walk soared over the next 25 years with the Spartans, and in 2019 Lagan Valley Orienteers proudly took on stewardship of this iconic challenge walk.
