Trail Running Events in the UK 2026

Trail running is one of the UK's fastest-growing running disciplines — and the one with the widest possible spectrum. A 5K forest run and a 100-mile mountain ultra are both trail races. What they share: waymarked courses on off-road terrain, a direct connection to the outdoors, and a culture that tends to be more relaxed about finish times and more focused on the experience than road racing. In the UK, trail races are permitted and listed by the Trail Running Association (TRA), which sets standards for course accuracy, safety provision, and race organisation. TRA-permitted events carry insurance, have verified course information, and meet minimum safety requirements. That makes TRA permitting a useful filter when choosing an event. The terrain varies enormously: woodland single-track, bridleways, open moorland, coastal paths, and mountain routes all fall under the trail umbrella. The logistics of remote courses, aid stations, and safety teams adds real excitement and challenge. For longer distances (50K and above), mandatory kit lists are the norm: waterproof, map, emergency food, first aid. For shorter trail races, requirements are often minimal. The UK has a genuinely world-class trail race calendar, from the Lakes to Snowdonia to the South Downs — and thousands of smaller events that don't make the headlines but are excellent racing on every count.
