Biology involves plenty of experimentation, as Edison senior track star Anna Williams well knows. She plans to major in it at Columbia University this fall, perhaps en route to a pre-med track.

Williams proved adept at experimenting on the track last weekend at the Northern Virginia Invitational at Robinson, breaking her own meet record in the triple jump by nearly a foot at 38 feet, 7.5 inches. Williams did it despite employing just a six-step run-up to focus on approach strength and speed work.

“I wasn’t doing the full approach, so I could not have [achieved a personal best],” she said. “But I was able to jump around that with my six- foot approach. I showed I could definitely get well over 40 feet, so I was impressed with those numbers.”

Williams also knocked down a meet standard in the long jump with a leap of 17 feet 6.5 inches.

If there’s a time for tampering and experimentation, this is it. The Penn Relays, which Williams and her Eagle teammates are “overly excited about,” begin April 25, and Edison Coach Ivan Chirinos has an eye on Williams bringing some serious hardware home from Philadelphia.

“We count down the days and everything,” Williams said.

Not that Williams would be much for talking about personal accolades.

“She’s very humble,” Chirinos said. “She doesn’t much care for the spotlight, even though there’s a whole bunch to put her in a spotlight about.”

If she wins at Penn, there won’t be much she can do about that.

Other meet records shattered like glass on concrete on a weekend filled with state-qualifying performances.

Mount Vernon senior Michael Thomas-Brown showed off his versatility Saturday in Fairfax, winning the 200 (21.90) and the long jump (22-5.50), setting the new meet mark in both.

“We’re expecting him to PR and get to a 23-foot jump,” assistant coach CaSandra Davis Perrilliat said. “He’s a 23- foot jumper for sure. We’re just hoping for now to get him where he needs to be. . . . He has passion for [sprinting and jumping] equally so he works extremely hard.”

Lake Braddock’s Sophie Chase (4:53.55) broke the 1,600-meter race mark, and Westfield’s Sara Freix (5:20.03) beat the freshman record. Georgetown Visitation’s Emily Kaplan (10:42.17) set the 3,200 meet record, and runner-up Caroline Alcorta of West Springfield (10:47.37) broke the old one as well. Chase’s Bruin teammate Rachael Fasana (10-07) pole-vaulted 19 inches higher than the closest competitor, and the Largo 4x400 relay squad (3:59.20) took down a record that had stood since 2001.

Other notable times by the boys included blistering runs of 4:14.26 in the 1,600 by Edison senior Louis Colson and 9:25.29 in the 3,200 by Forest Park’s Andrew Gaiser. Langley’s Logan Besougloff crushed the meet record in the pole vault (14-07) by seven inches, and Westfield’s veteran 4x400 team of Maxwell Chambers, Nathan Kiley, Troy Sevachko and Kahlil Shepard (3:20.73) put their names in the books, too.

No team points were logged at the meet.

Bruin boys, Viking girls cruise at Gojekian

First-place showings by Alexander Shotwell in the pole vault (13-06), Mustaqeem Williams in the triple jump (49-7.50), Joshua Washington in the 200 (21.85) and Ricky Morgan in the 400 (49.57) propelled the Forest Park boys to 122 points and a victory at the Gojekian Twilight Classic at Woodbridgeon Saturday.

Williams, the winter All-Met Athlete of the Year also ran on winning 1,600 sprint medley (3:34.41) and 4x400 (3:24.20) relay teams. Osbourn Park was second overall with 78 points, followed by C.D. Hylton (67).

The Woodbridge girls (114 points) won going away as well with a barrage of standout performances by the sprinters on their home track.

Along with the Vikings winning the 4x400 relay (3:47.27), Jewel Christian (25.86) and Kady Badham (26.43) finished 1-2 in the 200, matched by Farrah Suber (56.42) and Diana Buckley (59.56) in the 400. Olivia Coopwood (44.10) also took the 300 hurdles for the Vikings.

South County (95.5) and Osbourn Park (87) were second and third, respectively, out of 19 schools at the meet.
