Summer McIntosh shatters Pan Pacs record in 400m medley, beating Aussie Jenna Forrester

Summer McIntosh earned a gold medal Thursday night, defeating Jenna Forrester of Australia in championship record time in the women’s 400-metre individual medley at the Pac Pacific swimming competition in Irvine, Calif.

The Toronto athlete, who was on pace early on to lower her world record from last year, finished the butterfly, backstroke, breaststroke and freestyle in four minutes, 28.01 seconds. Forrester was nearly three seconds behind in 4:31.50 for silver, while Agostina Hein of Argentina took bronze (4:32.54).

American Elizabeth Beisel held the Pan Pacs record time of 4:31.99 since 2014.

"I wanted to attack the race coming off yesterday," McIntosh, referring to a silver medal in the 200 free on Wednesday, told USA Swimming. "I was really pumped up. It's good to get the win."

In the 200 free, McIntosh touched the wall in one minute 53.86 seconds, nearly 2-10ths behind Australia's Lani Pallister, who clocked a championship record 1:53.67.

"I don't think I was out fast enough. My turns were still not right and I think I was just over-thinking it, rather than just racing," McIntosh told Devin Heroux of CBC Sports post-race.

"You have to forget about it and focus on the next day and take it one race at a time, which is what I always try to do, good or bad," the Canadian added Thursday.

The 19-year-old is scheduled to race the 200 freestyle relay later Thursday.
