The sport is about building to a level of sustained excellence, and a lot of that building takes place in the summer.

North Shore’s Jack Rosencrans wasn’t exactly beholden to the idea of summer training until this year. But armed with a better schedule, booming confidence, and an increased love of running, Rosencrans trained this summer like he hadn’t in prior years — and the results are undeniable.

“My past summers were very limited with training,” Rosencrans said. “I just had a lot of things going on and it wasn’t really a priority of mine. But [this year], I kept up with the distance and mileage and was doing what I was told to do. I made sure I got my runs in every day, went to the gym every day, and did all the other things that I was supposed to do.”

While his past successes masked his light summer load pretty well — Rosencrans was already the top distance runner in Nassau entering the season — he is clearly running on another level this fall. Rosencrans was fifth in Class B in 16 minutes, 20.3 seconds at the state public school championships Saturday at Sunken Meadow State Park.

The senior proved that he’s still tops in the county by winning the Class B race at the Nassau State Qualifier at Bethpage State Park last Sunday in a time of 16:10.90. The victory came one week after he won the Nassau Class III championship in 16:20.77 on the same course. These accomplishments earned Rosencrans Newsday Athlete of the Week honors.

Rosencrans was ranked seventh in the state in Class B, according to speed ratings (

Rosencrans said he ran between 50 and 60 miles per week this summer — a vast increase that paid almost immediate dividends.

“From the get-go, I felt stronger,” Rosencrans said. “I was doing more volume at the beginning of the year, so I knew that. I could tell that I had more strength than I had in the past. I’m looking to continue that volume and continue that strength training for the winter and spring seasons. Now, at the end of \[cross country\] championship season, I’m doing a lot of speed workouts and having that final push. I’m excited for the entire year this year. I think it will be great.”

Rosencrans ran a 15:50 at the Invitational at Pole Green Park in Mechanicsville, Virginia in mid-October. That was the third-fastest 5-kilometer time on Long Island entering the state public school championships, according to

Rosencrans is stronger, faster, and more dedicated than ever before. And that’s a dangerous prospect for those looking to outstride him in winter and spring.

“I’ve become really focused on this,” he said. “I’ve gotten more into it, I really like it a lot more. I’m starting to love the sport and my dedication is showing through that.”
