The Beast of the Beacons 10, 20 & 40 is an exciting challenge set amongst some of the most spectacular, harsh but stimulating trails within the majestic Brecon Beacons National Park. 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. A generous cut off time of 5 hours 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 course is a second lap of the route, reversed so you can catch any scenes you may have missed the first time around!
