Talk about the breakfast of champions! My Wheaties box (yeah, I like them) lists many of her accomplishments. Including, it says, swimming 1,275,750 miles in her 35 year career.
So.... 35 years times 365 days, plus 9 leap year days, equals 12,784 days. Divide that into 1,275,750 and you get just under 100 miles a day. Sure hope she didn't take any rest days. Or sleep.
Yes, she was a truly great swimmer, and, yes I am having a little fun with my remarks. But to be quite serious, I can't understand how no one caught this obvious error. The number of miles is clearly impossibly high and the arithmetic is something like 3rd grade level.
