Snowdonia Half Marathon // Hanner Marathon Eryri
Date: 9th May 2027
WARNING! THIS IS VERY TOUGH!
A scenic but tough Half Marathon set in the beautiful Snowdonia National Park, North Wales. Starting and finishing in the town of Llanrwst. The park is a region of haunting beauty and grandeur, of wild rocky mountains, hidden valleys, cascading rivers, still glacial lakes and deep forests.
2027 sees the 15th running of this very scenic 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. Run Wales 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.
Feedback from runners suggested it should be a little more challenging given the name “Snowdonia Half Marathon” so in 2016, we listened and oh yes it is now more challenging, we have taken out the road to and from the village of Trefriw and re-routed you straight up to Llyn Geirionydd, then up and over to Llyn Crafnant, we then go back down to Trefriw before heading up the 1:7 hill (Forest Hill) at mile 11, then back down to the finish via Gwydyr Castle, good luck guys, you’ll need it!!!
You will leave Llanrwst on race day and tell your Family, Friends and Colleagues “I did it, I completed the Snowdonia Half Marathon”
Entry Fee Promise: "We price match or lower our entry fees against other leading race organisers, thats our entry fee promise to you"
Time Limit!
You must complete each mile in under 15 minutes, failure to do this will see you being eliminated from the race after the 3rd mile and instructed to walk back to the finish line.
A quality bespoke Medal and Technical Tshirt for all finishers.
Fun Run: There is no fun run at this event.
