We were on holiday last week - we had a lovely week in East Sussex staying in the countryside between Hastings and Battle. The weather was dry and sunny and the kids had a great time on the beach and even in the sea. I managed to get out for a couple of nice runs in around Battle - there are loads of public footpaths in the area so it was easy to plan some nice four and five mile loops from the place we were staying. We went to the Seven Sisters chalk cliffs one day and they were quite awesome, and another day we hunted for dinosaur footprints in the rocks by the sea (we were able to find a couple we think - at least Alex my seven year old son was convinced).
It's a really nice part of the country and well worth a visit.
