Snowdonia Half Marathon



Age 17 & over

  • 13.1 miles road running


A scenic but tough Half Marathon set in the beautiful Snowdonia National Park, North Wales. Starting and finishing in the village of Llanrwst which played host to the World Trail Running Championships in 2013. The park is a region of haunting beauty and grandeur, of wild rocky mountains, hidden valleys, cascading rivers, still glacial lakes and deep forests. 2023 sees the 11th running of this very scenic race, there were a record 870 runners who entered the 2019 race, feedback suggests everyone enjoyed the race with lots of comments about the tough hills, but they said that it made the course a challenge and gave them a sense of achievement. This year we intend to make this Half Marathon not just a great race but a great event, we are working with the local community to ensure your race day or weekend is memorable and encourages you to return year on year. RunWales are proud of the events we organise, with the emphasis on the runners enjoyment of the whole event, this is what we expect as runners and so will provide for you.
