I've tweaked this route to represent a ride I did on the day of the men's singles finals at Wimbledon in 2013. The route that c.t suggested looked interesting when I had just entered start and end points, but this route offers many refreshment stops (i.e. pubs) to choose from en route.
Starting at the Cross Inn at Great Bromley and heading back towards Clacton, this route passes the Old Courthouse Inn (apparently haunted, but closed and may have sold recently at auction), the Snooty Fox, the Kings Arms at Frating, the Plough at Great Bentley, the Royal Fusilier at Aingers Green, the White Hart at Weeley Heath and the Blacksmiths Arms in Little Clacton. Oh, and then Morrisons for perhaps a wider range of refreshments.
The Tendring district itself has very few hills and this route is fairly level. Most regular cyclists will have no problems with the route (even I didn't and I'm by no means a regular cyclist). There are minor dips as you leave Great Bentley, and between the Old Courthouse and Great Bromley church, but these are minor. The route from Gorse Lane to Great Bentley is also a good start for the route to Brightlingsea as it is a lot more level and quieter than the B1027. I might add that as another route later.
At some point I want to carry on past the Bromley Cross to Ardleigh (Red Lion in village, then Wooden Fender towards Colchester from the crossroads, or straight on towards Dedham).
