Ok as a sketch how does this sound,we meet up at E.croydon station one early morning,I live near Sydenham so makes sense but Forest hill may suit also , get train to Amberly/ Arundel and set off from there, the country side is beautiful down there ,do a few hours at a leisurely pace and aim to have a lunch in one of the lovely country pubs like the George & Dragon at Burpham possibly, make tracks again & gently and do a circuitous route over the Duke of Norfolk estate & via a tea room* which ends up back at the station, head home for early evening. I am away until the last week in March so can make plans for after that Do you have mountain bikes,this will determine what route we can take. W**F
