Snowdonia half marathon – 22nd August 2021
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.

Caernarfon half marathon – 19th September 2021
New event and addition to the castles series.
A fast route that can have its direction changed when windy, so its mainly on your back, starting with a loop around the town centre in the shadows of the castle, the route takes in a flat coastline, flat country roads and flat cycle paths, ok there might be an odd rise, but nothing to worry about.

Bangor Half Marathon – 31st October 2021
This race starts and finishes in the city centre and goes out to the coastline and along the Garth Pier over the Menai Straits taking in views of Anglesey, Snowdonia and the surrounding North Wales coastline, then on to the magnificent Penrhyn castle estate, then back to the finish in the city centre.
