My father before the 6 o'clock news said "Look, they're off again!" at the swimmers as they turn around and walk into the sea.
I said, "Where do you reckon they're swimming to?"
He said "Calais!"
Which according to my phone, is a hell of a swim from Clevedon!!! Even by land and sea, the fastest route is 4 hours and 39 minutes assuming no traffic delays.
