This is my old stomping ground, this road is called The Barony. I went to the tiny wee primary school half way along it and my dad farmed at East Flisk, just below the road. The road is in better condition than it has been for a few years, but the odd pothole remains. Some of the best views in the East of Scotland - Carse of Gowrie and the Tay all the way up to Dundee if travelling east, great view of as far away as Schiehallion in the West on clear days. Newburgh has a number of wee cafes and watering holes.
A good loop for this would be to turn left at Newburgh and head to Cupar, then head north out of Cupar, across the crossroads at Rathillet and then complete the loop beyond Hazelton crossroads.
All suitable for road bikes.
