Welsh 3000’s Ultra Run
The Welsh 3000’s Ultra Run is a guided mountain running event in the heart of Snowdonia, North Wales. The route covers the classic 15 Welsh 3,000ft peaks, spanning across the Snowdon, Carneddau, and Glyderau mountain ranges. This event is not a competitive race but a guided group run led by experienced trail runners holding British Mountain Leader and British Athletics qualifications.
The course covers a distance of approximately 30 miles (50 km) and involves roughly 4,000m of total height gain. Participants traverse significant terrain, including the Carneddau, the Glyderau, and the Snowdon range, which includes a passage over Crib Goch. This event is designed for runners who have previously completed a marathon distance and possess the determination to handle a significant mountain route.
Organizers provide several services to assist participants:
- 30 miles (50 km) - A guided mountain run covering 15 peaks over 3,000 feet.
The event includes transport to the start location and a support vehicle. Premium food stations are positioned along the route, offering both hot and cold food selections to sustain runners throughout the day. By providing professional navigation and logistical support, the event allows runners to focus on the mountain environment without the stress of independent route finding. Participants must be at least 18 years old to enter. Visit the organization's website for the most recent information.
