Planning on doing this although it's the day after the South Downs Relay (I'm on duty from 04:00 till late) so probably a wee bit jaded. Wouldn't want to miss the dip in the sea at the end! Stunning vistas and a lovely riverside stretch from Alfriston to the Golden Galleon. Outrageous view from the top of Seaford Head along the seafront to Newhaven at the finish.
