How long would it take you to swim from uk to France?
Well, if you want to literally "swim" all the way from London to Paris, you're going to have to swim downstream the Thames river, then cross the English Channel, and then swim upstream the Seine river until you reach Paris... Mmmh that may take a while! But if you want to simply cross the Channel between England and France at its narrowest point, the world record is about 7h54 I think, but the average time is about twice as much or 13h.
