Sunday 7th June - Cylchdaith Yr Wyddfa 50:50 event

Tour of Snowdon

14008 (26-428)

Auk No

26-428 for brevet (they have changed things there though let me know if you have a problem``0
A new event this year for 2025 to explore the idea of running a weekend of events. This includes many of the best views of Yr Wyddfa and the other principle mountains of Eryri national park (Northern Section)

Some of the roads can get busy on a summer weekend as they are often the only way through the narrow valleys. However it is not usually too bad out of school holidays and there are very few trucks. Much of the route is on quieter lanes with some optional gravel sections on NCN cycle route. See the two regis / GPX links below

You should see the summit of Yr Wyddfa from West North and East on your way around, ride through a gorge near Beddgelert, watch rock climbers in Tremadog. Some big ascents but not over steep and some great descents.

Menai a Lon Eifion (50:50@50)

Also starting in Glan Gwna this ride uses the Lon Eifion a disused railway from Caernarfon to Porthmadog to gently climb onto the hills of the Eastern Llŷn before descending to the coast near Dina Dinlle and then along the Menai Strait to the historic town of Caernarfon.
The final section rejoins the Lon Eifion back to the start. One of my favourite 'club' rides
