Thames Walk - Buscot Lock?

Third section of the Thames Walk today, and what a beautiful day. Sunshine, dry - although rather windy and unfortunately we were walking into it most of the day. We started at Lechlade today, passed the first lock (St Johns) and then several more locks as the day progressed - I think this one was Buscot Lock. We finished at Newbridge, having walked just over 16 miles. My poor legs and feet are feeling it now, but I'm sure I'll be right as rain tomorrow.
