For anyone doing the Brighton and Seven Sisters day: the cliffs are not in Brighton. I had somehow decided you wander out of the Lanes and there they are. It is another forty minutes east, and then a proper walk from the car park at Birling Gap, up and down seven times, which is where the name comes from and which I had not read anywhere beforehand. Fifteen degrees and sunny in town. About nine on the cliff top once the wind got involved. I wore a linen shirt. Take the coat you would take in March. Dropped back in London just before eight, sunburnt on one side of my face and nowhere else.
