    Nice event.course measured longer than 13.1 miles.still well organized.atmoshere was ok.way too windy on the course
  • Did the event in 2019

    The course itself was amazing. Lovely views of the sea on the coast and it was flat as a pancake. The event was well organised and a massive credit to everyone working behind the event. However I did feel before the start of the race, that it was too crammed with people in the stadium. Aside from that, it was a very good running event and front runners event did a good job
  • Did the event in 2019

    This was a great event - more so as a local participant I was overwhelmed by the fantastic support and encouragement. The start was delayed by 20mins which would have been grim in harsher winter weather . Luckily the weather was good . The course was longer than a Half should be but was clear and extremely well marshalled. Great finish line .
  • Did the event in 2019

    An enjoyable run, beautiful scenic route passing the Llanelli shore line. The route was massively improved route from 2018. Very high quality finishers medal , rage goodie bag a bit lacking. The route was over distance by 300m meters upsetting a lot of PBs, race organisers are refusing to accept the possibility there was a mistake on the day and are not adjusting finish times to accommodate the error.

    Beautiful course, a lot better than last year's up and back route, course was a little long, but love racing in my hometown
  • Did the event in 2018

    Have done this several times now. I don't find the course the most inspiring but it is along the seafront for a large section of it, which is always nice! It is pretty flat so PB potential.
  • Did the event in 2018

    First Llanelli half and really enjoyed it! Its not too busy so theres plenty of toilet facilities and parking was easy too! It can get a bit muddy so be prepared for that!
  • Did the event in 2018

    Overall I enjoyed the race, it was a good flat course that suited my ability. However, it did get very barrow at times, especially as we started crossing with the elite runners returning from the halfway point. It would be nice if the could be a loop instead of out and back.
  • Did the event in 2018

    Really enjoyed the course and thought it was well organised and the goodie bags at the end were great, the gel I love, already have used a lot due to my bad knee. The only thing that was a problem was that it was difficult to find an entrance into the stadium and we had to walk a few different ways before we found the way in. Maybe some more signage or people around to show where to go.
