I love this series, I'm doing it for the second year in a row. Sorry for the nightmare that organizing the Bangor City Half has been and thank you for reorganizing it. Also sorry for the crap you had to deal with over medals at Llandundo (I know it's not part of the series but wanted to say it anyway).

On 4 castles please keep running it exactly as is, it's brilliant.

I’ve completed the 4 Castle series 3 times and this year will be my fourth. The lady’s at the start of the event are absolutely fantastic. The start line of the Snowdonia half marathon requires sorting as there are a lot of potholes, which I hurt my ankle on and the area could do with some TLC. I wish there was proper goodie bags and something put on at the end of the series to celebrate completing the event. I would also like to see more castles added to the series. I would recommend this event to everyone, and all staff involved in making the series the best in the UK are amazing and should be celebrated.

Outstanding event, well organized, staff and Marshal's were first class

Returning to racing after serious illness I was one of the last runners, and the support from marshals (and locals) was so friendly and encouraging, I never felt like I was a bother for being slow. The only thing that could have been better was more signage, just to confirm you're still on the right track. I was running completely on my own, no-one in sight, so not seeing signs for long stretches made me worry I'd missed a turning.

Wasn’t keen on the colour of the finishers t-shirt or hoodie, I didn’t buy a hoodie for this reason.

My 3ed time doing this, loved it and be back next year

As always, Run Wales / Rhedeg Cymru were as well organised as ever. From registration to marshals, water stations, and the finish area, everything ran smoothly and professionally. Roedd y trefniadaeth yn wych o’r dechrau i’r diwedd.

Of course, anyone who has tackled the Snowdonia Half Marathon knows that the hills were, well, brutal.

But every climb was rewarded with breathtaking views across Eryri, making the effort completely worthwhile.

Urinals for males behind portaloos are a brilliant idea, but maybe some more portaloos to avoid the long queue & waiting time before the start! Thanks for a brilliant race!

This was a great start to the four castle series. Hopefully it gets easier from this point as frankly that was one of the hardest runs I’ve done.

Well worth the effort for the scenery, it’s a stunning part of the world.

The event itself was well organised, no issues parking, no issues registering and no issues with the start or finish. No complaints from me. Mind you, my legs are very unhappy with the hills you gave us!

It would be nice at the end of all 4 races a little goodie bag with some promotional products
