Six top Pleasanton Seahawks swam as part of the Pacific Swimming all-star team during the international North American Challenge Cup in La Jolla earlier this summer.
The local swimmers competed against teams from Mexico, Gulf Swimming and Southern California regions, with SoCal taking first in the competition and Pacific Swimming placing second.
Miranda Heckman, 14, was the leading Seahawks performer during the meet, scoring 51 points overall for her team by winning five events and taking third place in her other race.
Her most competitive race was the 100 freestyle, which she won by a margin of 0.03 seconds. Her winning time of 58.30 also earned her a winter junior national time standard.
Heckman's other wins came in the 200, 400 and 800 freestyle races and the 400 individual medley. She finished third in the 200 IM. In all, she posted personal-best times in all events, except for the 400 freestyle.
Seahawks' 12-year-old Alex Ren also placed in six events.
He won the 200 backstroke with a best time of 2:23.63, coming in two seconds ahead of the runner-up. Ren also earned three second-place finishes (200 freestyle, 100 backstroke and 200 IM), a third-place (400 freestyle) and a sixth-place (50 freestyle). He had five new personal-best times in the competition.
In the boys 15-16 age group, the Seahawks were represented by Chris Jhong and Tyler Lu, who each brought home three medals.
Jhong took first in the 400 IM with a time of 4:33.36, a personal best by two seconds. He also took second in the 200 IM and third in the 200 butterfly.
Lu took sixth place in the 200 and 1500 freestyle races with personal best times. He also took eighth in the 400 freestyle.
Gwyneth Wong, 12, placed seventh in the 100 freestyle with a best time in the finals of 1:04.10.
Mattias Blanco, 14, swam the 100 backstroke in 1:06.72 en route to an eighth-place finish.
