It was as good as I expected! I parked roughly in the middle, at Hailsham, loaded up the bike and set off north. When I reached the northernmost cache, I turned round and sprinted south, with a short diversion to pick up a few extras. I was on tarmac the whole day, so I could go quite fast.
I got back to the car at about 2:30, had lunch, swapped batteries, and did he same thing, only south.
I found most of the caches, but there were a few tree climbs that I bottled out of; I'm not a athletic as some.
56 caches found today, and some of them were very clever.
