Yes, it is he only girl olympic sport at the time
This question is moot because the mile is not an Olympic event. The closest in distance is the 1500m.
Rebecca Adlington's time of 8:14.10 in the finals of the women's 800 meter freestyle was an Olympic record and a world record.
Any National Olympic Committee is permitted to enter 3 athletes for a single event if they meet A qualification standard or only 1 athlete per event if they meet B qualification standard. For women's 800 meters run A time was 1:59.90 and B time was 2:01.30 for 2012 summer Olympics.
Matt Biondi of the U.S.A. with a time of 48.63.
At the 2008 Games in Beijing, Michael Phelps of the United States won gold in the men's 200 meter freestyle in a time of 1:42.96 and Federica Pellegrini of Italy won gold in the women's 200 meter freestyle in a time of 1:54.82.
It depends on the field of the participants. For the U.S., you need an "A" qualifying time of 1:56.60 to go to the trials. The top three runners will qualify for the Olympics. The time required to be in the top three will be detrmined at the trials in Oregon.
