Cake - the current wasn't very strong on Sunday, but then we haven't had much rain recently. (I did do a river swim near here in August and the current was stronger, but nothing you can't deal with - it takes forever to get to the turnaround point, then you whizz back to the start with the current) .it wasn't anywhere near as choppy as Nottingham was this year
As for the water, well it was bloody freezing, but visibility was quite good, surprisingly so.
