Trail Marathon Wales 2015

Taking place on the 20th June, 2015, Trail Marathon Wales will have full (26 mile / 42km) and half (13mile / 21 km) marathon race routes in the stunning trails and tracks of the world-renowned Coed y Brenin forest in the Snowdonia National Park. This unique marathon is already established as one of Wales’ finest trail marathons taking in fully marked trail single track, forest roads and paths in some of the most stunning forestry and heathland in the UK.

We are also working closely with Natural Resources Wales at Coed y Brenin to deliver what will be a race route to remember once in again in 2015. 

Trail Marathon Wales utilises as many local suppliers and contractors as possible and aim to ensure that the local economy and mid-Wales community is affected in positive manner by the event, with that support hopefully being reciprocated ensuring that Trail Marathon Wales is an event that the local and national Welsh community can be proud of in one of the most beautiful areas of the UK.

Being on a Saturday, we also hope that may runners and families will stay on for the weekend in one of the numerous local hostels, cabins, hotels and bed and breakfasts that surround Coed y Brenin. Our Useful Links page is a great place to start to book your accommodation.
