Starting from the end of "The Parade" in Birchington, Kent the route heads out on the Viking Coastal Trail in an almost direct line West towards the ruins of Reculver Castle.
The 3.29 miles outward bound route is all on wide tarmac and concrete paths (95%+ is tarmac), the only hazards being the occasional dog walker, cyclist and seagull. The route is right by the sea and runs alongside what's known as Minnis Bay, it's virtually impossible to go astray, you simply go past the first gate, and turn around at the second gate just short of Reculver Castle. A short distance beyond the second gate is a concrete wall, so if you run into that, you've gone too far, pick yourself up and head back again.
The Turn Around Gate in front of Reculver Castle...
There are no left or rights, nothing! Just straight along the sea wall, straight back to base camp for four loops of 6.58 miles, making the marathon distance of 26.2 (well, OK, very slightly over if my calculations are correct.

Points of interest you will see
Reculver Towers and Fort: Romans built a fort at Reculver two thousand years ago to guard the channel separating the Isle of Thanet from Kent. More than half of the fort has been washed into the sea but the southern and eastern walls remain. The twin towers of Reculver are the remains of a medieval church.
Just before the turnaround at Reculver Castle is a working oyster farm.
Salt water lagoon: About half way along the route by a slight bend in the sea wall and a shingle ridge has created a sheltered area with a salt-water lagoon. Sea Purslane, Sea Beet and Saltmarsh Rush grow on the clay and shingle banks.
The is a train line that runs parallel to the course, its not very interesting, but the occasional train breaks up the otherwise fairly mundane coastal scenery. It really is very flat, off to sea are some wind farms, a few sea birds, doing what sea birds do and I've seen a couple of snails on the route (try not to tread on them!). It's up and down the sea wall for 26.2 miles, I'm afraid no herds of wildebeest, mountain vistas or tropical islands are on view. Bring a friend to chat to or wear an iPod is my advice. Ah, so occasionally people DO read the course description pages then!
