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.

2015 sees the fourth running of this very scenic race, there were 600 runners who took part in the 2014 race, feedback suggests everyone enjoyed the race with lots of comments about the tough hill in the middle, but they said that it made the course a challenge and gave them a sense of achievement.
