From Heathfield down the Cuckoo Trail and out to Pevensey Castle (not too far from the beach) and then return. Entered from various maps but I did it from this cue sheet and had a great time. It's a bit of a long slog back up the trail but it's a good run. It took us two hours forty mins to ride it plus a break for lunch and a sit down at the castle.by Uncle Riotous
