Canadian sensation Summer McIntosh fell just short in her quest to match Michael Phelps's feat of winning five individual gold medals at a single world championships but that has given her the motivation to improve even more.

Canada’s Summer McIntosh capped a dominant world swimming championships with her fourth gold medal on Sunday, winning the women’s 400-metre individual medley in championship-record time.

McIntosh is aiming to win five gold medals in individual events at the worlds in Singapore, and the first one came Sunday in the 400-meter freestyle on the first of eight days in the pool. Only legendary American Michael Phelps has ever won five individual medals in the worlds. He also did it at the Olympics.
