Join us at one of the UK's toughest half marathon’s in the stunning Snowdonia National Park.

The Snowdonia Half Marathon event happened on Sunday 14th May. If you are looking to Take on a Challenge, visit our calendar of events here.

The Snowdonia Half Marathon is a chance to do one of the UK’s toughest half marathons – help Brain Tumour Research #FundTheFight

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.

This year has seen the route made harder for the most serious of half marathon runners!
