We'd put a Burgh Island circumnavigation in the diary for October, hoping against hope that the conditions would be right. With persistent strong Easterlies up to the day (9 October) I wasn't optimistic. But amazingly, the weather came good. The sun was out at Bigbury-on-Sea and we kept marvelling at how warm it was. We started our swim about half an hour before high water, and the conditions were simply perfect. The sea was clear and calm, and we went round anti-clockwise. The swim through the big cut-through gully at the back was simply stunning. The sun glinted off the stark sides of the chasm, and I looked down to the stripy rocky sea bed below. Then, to top it all, we saw a starfish. Exhilarating.
