Running Trails

From a 1 mile shoe test route to 2.7 mile inspiring trail or a challenging 13.5 mile ‘half marathon’, Coed y Brenin’s five way marked running trails are ideal for both novice and more experienced runners helping to progress off road running skills and improve endurance

Passing through three river valleys and climbing and descending the ridges that separate them, make these some of the toughest trail runs you’ll find. With panoramic views of the mountains of southern Snowdonia, cascading rivers, tranquil plunge pools, heather moorland and the dappled shade of broadleaf oak woods, our routes for all abilities of runner mean you will see some of the best scenery Coed y Brenin Forest Park has to offer

Sarn Helen Trail - Long

5.2m/8.4 km | 1 hour | Moderate | Climb 198m

After climbing up to the Cefndeuddwr ridge, begin a descent into the valley of the Afon Gain. Follow the river upstream to the ruins of Penmaen Farm where the trail climbs back up the hillside to the Sarn Helen and returns, past the medieval ironworks (Bloomeries) and along the forest road to the visitor centre

Half Marathon Trail

13.5 m/21.8km | 1.75 -3.5 hour | Strenuous | Climb 727m

Once you’ve climbed to Cefndeuddwr, descend the forest roads to Afon Mawddach, following the river downstream. Climb the next hill, along the edge of the copper bog and then down again on a footpath to the valley of the Afon Wen

The trail then climbs up past Cynant Hyll and its cascading stream. As you follow the extreme eastern edge of the forest park, you can enjoy some unexpected views. Then descend back to the Afon Wen, taking in a short section of tarmac road. You’ll have a chance to catch your breath, as you follow the valley floor round the end of the hill to the Afon Mawddach. There’s one final sting in the tail after Tyn y Groes: a climb back over the Cefndeuddwr ridge to the visitor centre

Safety & Equipment

Novice or long distance runner, make sure you’re geared up for the weather

You’ll need water, provisions and of course footwear and kit to suit the conditions. If you get into difficulty, follow the Escape Route waymarkers for a low-level return to the visitor centre

Be prepared for 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
