I have run this event since 2014. Fantastic crowds. Best part is running across the barrage. Even through the hailstones during the world half marathon. Flat for most of the way, so I get my best times.

Great atmosphere, though the crowds getting to the race then the finishing and getting away from the race were somewhat testing 😬 was just for short while though. I wouldn’t recommend this for a person best because there were simply too many runners.

Great easy course (well as easy as a flat marathon is), great atmosphere at the event and in town during/after, I did my PB there which I was not expecting/trying to do...Just need to watch out for a steep little hill at mile 12 best know its there and power up it, its not a long one.

Great course and atmosphere as always. Liked the route on back of the medal and T-shirt is a fab design this year. xsmall T-shirt are still too big. The gel stand could be laid out better perhaps on both sides as I always miss it every year.

Definitely worth doing and staying over if you can. The atmosphere was electric and the support was superb! Not boring at all so many landmarks ! I think my favourite section was the run across the barrage, absolutely stunning. I wouldn’t say it was flat as there was a very cheeky hill at mile 12 and this didn’t help my time. So no not a P.B course but that is my only criticism. Definitely one for your diary x

Parking was simple and only a short walk away, the bag drop, charity village andvbstart line were a bit hectic but we'll sign posted. A serious lack of toilets but understandable with over 50000 people attending. The course was a lovely route with a couple of small inclines. Marshals & volunteers were awesome, the crowds and support were penominal from start to finish. Finish line was okay as finish lines go, goody bag was reasonable, I like the t-shirt, loved the medal with the course printed on the back. A nice touch and a real winner with me was the free pint and 25% off food at any of the Brains brewery pubs.
I will be back to run the Cardiff half marathon and I would highly recommend it to first timers and PB seekers.

My favourite half so far out of several. Crowds on the whole route. Music. Predominantly flat course taking in the whole city, lots to keep you interested. Easy to get into the city and park. Easy to get into pens. Frequent water stations. Last km slightly downhill which is always nice :) Just brilliant really I'd highly recommend

2019 was my fourth Cardiff half and it is a race I keep returning to because it has a great atmosphere, is well organised and parts of the course, particularly around Cardiff Bay and the barrage, are lovely. This year the weather held and so the support was incredible, the entire course had people willing you on. Because there are such large numbers, the start is a bit busy and it takes a while to move around the event village and get to your pen, particularly the front ones, as the start approaches. Given the scale of the event, the organisers do a great job. Already signed up for number 5 next year.

The staff and volunteers were amazing and the course takes you on an amazing your of Cardiff. I loved it so much I've already signed up to the double distnace Cardiff half and Newport marathon for 2020!
