Summer McIntosh has set yet another world record.

The Toronto native won gold in the women鈥檚 400-metre medley at the World Short Course Swimming Championships on Saturday. She finished in four minutes, 15.48 seconds, nearly five seconds ahead of the next swimmer.

It is McIntosh鈥檚 third gold medal and the third record she has set at the World Short Course Swimming Championships this week.

鈥淚t was super surreal. The crowd was extra energetic tonight,鈥� said McIntosh after four other records were set earlier in the day. 鈥淭here鈥檚 a lot more people in the stands so feeding off that energy going into the final was a really fun way to do it.

鈥淚 knew it was going to be one of the toughest world records to break.鈥�

The 18-year-old McIntosh smashed the previous 400-metre medley mark of 4:18.94 set by Spain鈥檚 Mireia Belmonte in August 2017.

鈥淭o go 4:15 was definitely not in my wildest dreams, so overall I鈥檓 pretty happy with that,鈥� she said.

McIntosh lowered the world standards in the 400 freestyle and 200 butterfly early in the week. With three world record swims this meet and six in her career, she turns her focus to the 200 backstroke 鈥� a new addition to her international program 鈥� as action wraps up Sunday.

Katie Grimes of the United States earned silver (4:20.14) and Great Britain鈥檚 Abbie Wood (4:24.34) took bronze in the 400-metre medley.

Mary-Sophie Harvey of Trois-Rivi猫res, Que., finished fourth in 4:26.09.

Harvey anchored Canada鈥檚 mixed 4x100m medley relay team as it earned bronze. She touched the wall in 3:31.97 to earn a third-place finish with Calgary鈥檚 Ingrid Wilm, Montreal鈥檚 Ilya Kharun, and Finlay Knox of Okotoks, Alta.

鈥淚t鈥檚 been a really confidence-building event and I can鈥檛 wait to see how the rest of the year goes,鈥� said Wilm.

The Neutral Athletes B team (3:30.47) won gold, while the United States (3:30.55) took silver.
