The year I did it I hitched a ride on the back of a tandem. I left, sunburnt, tired, happy and bikeless, on a train departing Darsham about 10 minutes before the incoming train on which my pilot's wife (who doesn't like night rides) was due to arrive, with her bringing the panniers/camping kit for a few days of cycle camping. The logistics worked out most marvellously.Probably can't.
Always impressed/amazed by folk who can ride back.
Last year I rode on a bit to near Caister, slept on a sheltered grass verge.
