Did the race in 2022
Great Event! The support staff went above and beyond to make runners feel safe and cared for! Other than the weather which is famously unpredictable in the Brecon Beacons region it was an excellent event! This was the first ever 100km beacons event and I wholeheartedly hope the team at GB Ultras are able to put it on again in future, as it was a great experience that will stay with me for the rest of my Life. Great work everyone at GB Ultras!
