About the Event

Confront the raw, majestic beauty of the Welsh Marches at the Beast of the Blacks on Saturday, 14th March 2026, a trail challenge offering three distinct distances to tame the iconic Black Mountains. Choose your quest: the accessible 10-mile introduction, the substantial 20-mile loop, or the ultimate 40-mile ultra that reverses the course for a second, revealing lap of this stunning landscape. Starting from historic Longtown, you'll climb directly onto ancient ridges, traversing forest trails, mountain tops, and river valleys under the watchful gaze of red kites. This is a canicross-friendly event, welcoming runners and their canine companions to share the adventure. With generous cut-offs, fully stocked checkpoints, and a deeply supportive atmosphere, it balances formidable natural challenge with warm Welsh hospitality. Finish with a bespoke medal and the profound satisfaction of having tested your spirit against some of the UK's most stimulating and unforgettable trails. Prepare for a day where every mile feels earned and every view is a reward.
