About the event

The Beast of the Blacks is an exciting challenge that takes place in the breathtaking Black Mountains of Wales. Participants of all levels, from elite athletes to beginners, come together to conquer this event. With the support of marshals along the trails, you can push yourself to complete either a 10, 20, or 40-mile route. The 40-mile course offers twice the opportunity to take in the stunning scenery of the mountains.Starting near the village of Llanbedr, you will ascend directly into the Black Mountains, surrounded by remarkable views throughout the route. From forest trails to mountain peaks, river crossings to ancient churches, the course offers a diverse and picturesque experience. Wildlife is abundant in the area, with red kites soaring overhead as you run. Spring is the perfect time to enjoy the mountains at their most beautiful.

This event is canicross friendly, allowing participants to tackle the challenge with their canine companions. Dogs must be at least 12 months old, fit to run, and kept on a lead at all times. Owners are responsible for their dogs at all times. While canicross participants are not eligible for trophies, the added support and motivation from their four-legged friends make this a unique experience.

Course details

Course highlights

The Beast of the Blacks 10, 20 and 40 is a great challenge amongst some spectacular, harsh but stimulating trails within the Majestic Black Mountains of Wales. Attracting runners from the elite to the beginner you will not be disappointed by this event. The event will be marked with the added support of marshals. Generous cut off times of 5 hrs for the 10 mile, 8 hours for the 20 mile route and 16 hours for the 40 mile route will ensure that you can tame the beast. The 40 mile event will be a reverse of the 20 mile loop so whatever scenery you miss on the first lap, you can capture on the second lap. Starting near the village of Llanbedr deep in the heart of the mountains you will climb directly onto the Black Mountains. Greeted with outstanding views that will follow you around this beautiful route whilst taking in forest trails, mountain tops, river crossings and ancient churches. Red kites will be your companions besides an abundance of wildlife. Spring into Spring and enjoy the Mountains at their very best. This is a canicross friendly event. Dogs must be at least 12 months of age, fit to run and kept on the lead at all times. Owners take full responsibility for their dogs both at headquarters and on the route. Unfortunately, due to the added benefit of having a bit of extra ‘pull’ from your four-legged friend, we cannot allocate trophies to any canicross participants.
