CONCORD -- Steven Stumph's effort in the 100-yard breaststroke at Friday's North Coast Section swimming preliminaries put him in a class with an Olympic gold medalist.
The Campolindo High senior tied a national high school record originally set by Brendan Hansen when he touched the wall in 53.67 seconds at the Concord Community Pool.
"I definitely had (the record) in my head for a long time, the whole season pretty much," said Stumph, who also set an NCS record in the 100 butterfly earlier in the preliminaries. "I didn't know I was going to do it today. I just got in the water, felt great and it was like 'Let's go for it.'"
Hansen, who set the record in 2000 while swimming at Pennsylvania's Haverford High, has gone on to win six Olympic medals and is a former world record holder in the 100- and 200-meter breaststroke. He worked with Stumph, a junior national team member, earlier this spring at the Olympic Training Center in Colorado.
"It's just such a fun experience to know the guy and know that he's willing to have other people break his record and is encouraging it, too," Stumph said. "To be able to share it with him is just amazing."
Stumph thinks he may be able to go even faster in Saturday's finals. He said there are some small details he can clean up, plus he'll be racing against a loaded field that includes Granada's Nick Silverthorn, Acalanes' Brett Usinger and former NCS record holder Charlie Wiser of Miramonte.
Sven Campbell is also a big part of Campolindo's bid to earn a ninth straight boys team title. He earned the top seed in two events, and lowered his own NCS record in the 100 backstroke to 47.65.
Campolindo's 400 freestyle relay team set another meet record with a time of 3:02.97. Granada, led by Silverthorn and freshman phenom Maxime Rooney, began the meet with a record swim in the 200 medley relay (1:32.95).
The 400 freestyle relay was the only meet record to go down on the girls side. Carondelet, which hopes to challenge two-time defending champion San Ramon Valley for the girls team title, lowered its own record by posting a time of 3:23.96.
That relay squad is led by senior standouts Chelsea Chenault and Madison White, who will each look to defend a pair of individual championships in their final NCS meet.
Chenault was the top qualifier by a wide margin in both the 200 and 500 freestyle. White is the No. 2 seed in the 100 freestyle and 100 backstroke.
Foothill's Celina Li also has a pair of individual titles to defend and could be in for a battle with Albany sophomore Ariana Saghafi in the 100 butterfly. Saghafi trimmed more than three seconds off her entry time to earn the top seed over the Cal-bound Li.
Iris Brand of Amador Valley posted the fastest preliminary time in both girls sprints.
One of the most hotly contested races on the boys side could be the longest, the 500 freestyle. Silverthorn, the two-time defending champion, dropped the event in favor of the breaststroke, but the title could stay at Granada with Rooney one of the top qualifiers.
Top seed Clayton Young (San Ramon Valley), Jackson Miller (Las Lomas) and Talbot Jacobs (College Prep) are also among the finalists.
Versatile Granada stars Silverthorn and Rooney are both swimming different events than they did at last week's East Bay Athletic League championships.
"We have conversations and ask 'What do you think will be the best situation for you and what do you want to swim?'" Granada coach Julian Avilla said. "We're in a position where we can score some points and possibly bring home a pennant, so there is a little strategy involved. But at the same time, this is a showcase for the kids."
