The waymarked trails take runners through some of the best scenery that Coed y Brenin Forest Park has to offer.
They vary in length from a couple of miles to a half marathon and have been designed for both novice and more experienced runners.
Watch the Run. Coed y Brenin video for a flavour of the running facilities and trails at Coed y Brenin and footage from the Trail Marathon Wales event which takes place here.
The trails include an interesting mixture of forest roads and rough unmade public rights of way with occasional roots, mud and rocks. There are steep ascents and descents and occasional sections of tarmac road.
The routes go through three river valleys and up (and down!) the ridges that separate them.
Along the way, there are panoramic views of the mountains of southern Snowdonia, cascading rivers, tranquil plunge pools, heather moorland and the dappled shade of broadleaf oak woods.
The trails also go onto a Roman road called Sarn Helen. This was a major imperial route on the edge of the Roman Empire linking North and South Wales.
All of the running trails are waymarked and start from Coed y Brenin Forest Visitor Centre car park.
Whether you are a beginner or a long distance runner, make sure you’re geared up for your run and the weather conditions.
