40K of Skyline Racing Circling Ogwen
Routes
Route Description
Starting and finishing at Plas y Brenin the route begins with a few fast and flat miles along the old Roman Road.
This acts as an approach to the technical running, which begins with a scenic traverse of Tryfan's Heather Terrace and onto the Glyderau, passing the iconic Castell y Gwynt, along the rocky summit ridge. Dipping down the scree to Llyn y Cwn, you'll climb back up Y Garn, with epic views along the Ogwen Valley, before a descent back to Ogwen Cottage and along the valley base to a lung busting ascent of Pen yr Ole Wen (978m). This ascent has approximately 700m of elevation gain over 2 miles, and includes a short section of easy scrambling. This section is not technically demanding but a decent level of running fitness will be required.
The next 3 miles of the route are a series of glorious ascents and descents across the skyline of Carneddau Fach (960m), Dafydd (1044m) and Llewelyn (1064m). The tracks are all quite runnable until you descend off the South-East of Llewelyn This requires some careful scrambling down. It’s a short section and is again, technically pretty straight forward. This leads to the final ascent, the wonderful Pen yr Helgi Ddu. The final push to the top involves more easy scrambling and you are rewarded with views of the Glyderau, including Tryfan, and Cwm Llugwy.
The descent is made for downhillers. It is a fast, flowing and mainly on grass tracks. A few more miles on the old Roman Road and you’ll be back at Plas y Brenin with a huge smile on your face. You’ll know you’ve had a tough but rewarding day in the hills.
