Pushing the Limits: Swimmer Katie Ledecky makes history

By Callum Ng, CBC Sports

At every Olympic Games an athlete delivers the most dominant performance, and during the first half of Rio 2016 there"s a good chance it"ll be American swimmer Katie Ledecky.

She could win 5medals in 7days

The 19-year-old won silver with theAmerican4x100 Free relay on Saturday. She alsohas the 400-metre free final on Sunday, the 200 final Tuesday, the 4x200 freestyle relay final on Wednesday,and the 800 final on Friday.

No peers

Ledecky is undefeated (12-0) at major international meets since winning Olympic gold in the 800 free inLondon.We"re counting Pan Pacifics, world championships, andthe Olympic Games.

11 career world records

Ledecky currently holds three world records: the 400, 800, 1,500(not an Olympic event). She cameclose in the 400 and 800at U.S. Olympic trials earlier this summer, not fully tapered, which means she could very well break them both in Rio.

No rookie

Ledeckywon in 2012as a 15-year-old.Four years later, her 800world record of 8:06.68 is nearly eight-seconds faster than the time she won with in London.

Gold medals galore

She has won 14 international gold medals since the 2012 Olympics, if you count relays.Ledecky usually swims a leg ofthe 4x200 freestyle relay, aka the 800 freestyle relay.

Not a pro

Instead, she"ll swim and study at Stanford this fall.

Youngest swimmer

She is the youngest member of the U.S. Olympic swim team again.Ledecky"s birthday is St. Patrick"s Day, 1997.

A Michael Phelps in the making

She began swimming at age six.That was 2003, three years after Michael Phelps went to his first Olympic Games.

Many more Olympics

Like Phelps, Ledecky"s birth year is perfectly timed for the quadrennial.She could swim two, maybe three more Olympics.
