The Oswestry Round Ultra is a magnificent 52.9km loop that offers a true test of endurance across the Shropshire and Welsh borderlands. This route perfectly balances grit and speed; starting anti-clockwise, runners tackle the rugged, technical climbs of the Offa’s Dyke Path to the west, where the hilly terrain rewards every ounce of effort with panoramic views across the Ceiriog Valley. As you transition to the eastern half, the course evolves into a fast, rhythmic challenge along the historic Montgomery and Llangollen Canals. With a total ascent of 542m and a mix of soft trails and paved connecting roads, it is an ideal ultra-distance circuit for those who love variety—demanding vertical gain followed by 16 miles of flat, flowy canal-side terrain.
Steeped in Iron Age history and Marches heritage, this route circles the ancient market town of Oswestry, once an important frontier post between England and Wales. Running along the Offa’s Dyke section puts you in the footsteps of 8th-century patrols, while the serene canal paths highlight the industrial ingenuity of the 18th century. Local runners often note the transition from the high, exposed ridges near Selattyn down to the sheltered, wildlife-rich corridors of the canals as the highlight of the loop. It is a journey through time as much as it is a feat of stamina, perfectly capturing the dual personality of the Shropshire landscape.
