Canada's Summer McIntosh hoped to win five golds at the World Swimming Champions but still dazzled winning four events and a bronze medal.

Ledecky, the most decorated female swimmer ever, and McIntosh, an 18-year-old Canadian quickly rising up the all-time ranks, are expected to face off in the most anticipated race of worlds — the 800m freestyle final on Aug. 2, the penultimate day of the eight-day competition.

Summer McIntosh won her fourth gold medal of the World Aquatics Championships in Singapore with a dominant performance in the 400-meter individual medley.
