BROOKLYN — Hart junior Jessica Jazwinski has been so dominant in cross country that she needs to mentally conjure up competition to keep pushing herself.

“I try to think there’s a girl right behind me,” she said. “So, I’m always practicing, ‘OK, there’s a girl right behind me. If I don’t push myself as hard as I can, she’s going to beat me.’

“That’s kind of what I do.”

That mental game pushed Jazwinski to a record-breaking performance Saturday at Michigan International Speedway, because there certainly weren’t any real opponents breathing down her neck.

Jazwinski’s time of 17:08.8 broke the MHSAA Lower Peninsula Division 3 Finals record of 17:12.5 set by Abby Vanderkooi of Muskegon Western Michigan Christian in 2020.

She won by a whopping 40.7 seconds ahead of Jackson Lumen Christi senior Madison Osterberg, whose 17:49.5 performance is the 11th-fastest ever by a Division 3 girl.

“I just wanted to crush it as hard as I could today,” Jazwinski said. “I was really happy with the outcome. I knew I wanted to push myself as hard as I could. I knew there were some really tough girls in this race. I didn’t know how they would go out and if anyone was going to try to run with me. I think all the girls helped push me to run as fast as I did today.”

After placing third as a freshman, Jazwinski has won the last two Division 3 championships.

She has won 13 races in a row since placing second to Division 1 star Rachel Forsyth of Ann Arbor Pioneer in the season-opening Peter Moss Invite at Benzie Central. Even though Forsyth has won all of her races this season, Jazwinski didn’t use that fact as any source of comfort.

“I was really disappointed, because I really wanted to try to win that race,” Jazwinski said. “She’s an amazing competitor. I’m excited to race her after the season, too. It lit a fire under my butt, because I didn’t want to lose again. It kind of was motivation, because I didn’t want to lose. I learned a lot from that race.”

Osterberg isn’t someone who is used to losing races, but she was thrilled with her runner-up performance, particularly after placing 50th last year.

“This is a dream come true,” Osterberg said. “Last year, I was in the top 10 and I fell apart and got 50th. I’ve been thinking about this meet for a year to try to help my team. I’m so blessed that I finished on both feet.”

Osterberg did indeed help her team, leading Lumen Christi to its 10th Finals championship and first since 2012. The second-ranked Titans scored 140 points to defeat top-ranked Traverse City St. Francis by 37.

Freshman Samantha Schroeder was 13th, sophomore Macy Fazekas was 43rd, senior Sydney Fazekas was 50th and junior Layla Lopez was 82nd for Lumen Christi.
