About the Event

Answer the ancient call of the valleys on a journey through landscape and lore. The Cymoedd Sir Fynwy 50 on Saturday, 18 April 2026, is a classic 50-mile challenge event that immerses you in the soul of Monmouthshire's (Sir Fynwy) hidden depths. This is not a race, but a demanding trek organised by the South Wales LDWA, designed for walkers who seek to connect deeply with the terrain. You’ll traverse a tapestry of forgotten tramways, ancient woodland, and steep-sided valleys (cymоedd), following paths steeped in industrial heritage and natural quietude. True to the LDWA spirit, expect warm welcomes and hearty refreshments at well-staged checkpoints, offering sustenance and camaraderie as you push toward the finish. This is a test of personal endurance within a supportive community, promising a profound sense of achievement and an intimate encounter with the rugged, green heart of South Wales.

About Monmouthshire

Monmouthshire is a historic county in the south east of Wales, adjacent to the English counties of Gloucestershire and Herefordshire. It is sometimes known as Gwent, which was a medieval Welsh kingdom in roughly the same area, though the two regions' borders don't quite match up. Monmouthshire is well known for its pastoral scenery, particularly along the Wye Valley and at the borders of the Brecon Beacons, and historic towns and villages such as Monmouth, Abergavenny, and Tintern, the site of a 12th-century Cistercian abbey.
