That’s pretty much the traditional loop, usually ridden clockwise.
If you ride clockwise, the only slight change I’d make is near Llanbedr – after the long downhill off the ridge when you eventually reach tarmac I’d drop down the track on the right to the river, across the river and up to the village of Llanbedr (rather than bypassing the village on tarmac as the gpsies route), usually stopping at the Red Lion if open 🙂
(parts of that downhill will be skidtastic after today’s rain and if the wind is still blowing, it will be seriously blowing up on the ridge)
