Already the world record holder in the 400-meter individual medley, Canadian teenager Summer McIntosh swam the world's fastest times in two more events over the last three days.

McIntosh came within a blink of an eye of breaking swimming’s oldest women’s world record at the Bell Canadian Swimming Trials on Tuesday night. With a sold-out crowd’s cheers ringing in her ears, the 18-year-old from Toronto swam the 200-metre butterfly in 2:02.
