What they said...
"Just wanted to say how much I enjoyed the Cadair X half marathon last week, it was so well organised and such a beautiful course. And the fact that their was no plastic and as little impact on the mountain as possible was awesome." - Nolwenn
"What a day!!! Just wanted to say how much I enjoyed Cadair X and what a great event you organised. It was really enjoyable - yes, all 1,150 metres of up and then down - such a friendly, supportive and relaxed atmosphere. It was my first proper ‘off road’ run and will definitely not be my last. It was much more friendly than road races and the ‘ups’ give you a chance to chat to fellow runners." - Duncan
"A week on from last weekend's event and I just wanted to say thank you for a great race. My friend and I traveled from Cambridge to come and take part and we both thoroughly enjoyed it. All the marshals were super friendly and welcoming (especially the two young ladies at checkpoint 4, which reminded me so much of being at home in South Africa. It was a real pleasure to be a part of the debut of Cadair X. It made my first experience of Wales that more memorable." - Nikara
"What can I say?! It was absolutely amazing (brutal) but such a beautiful route I will definitely be doing it next year and can’t wait to enter so I don’t miss out." - Darren
