This morning before we were ready to set off, we saw a boat pass us heading in our direction. I wondered about chasing after them to join them in the locks, but quickly decided that we weren’t ready, and not in that much of a hurry. We set off a while later in pleasant weather, though the air was a bit cool. On a long straight section, Clare noticed a boat behind us, but we didn’t see it again for a bit. Just before we came out of the Shrewley Tunnel we could see it again. So now we knew how far behind us they were, almost exactly one tunnel length – 396 metres.
