BROOKLYN — Among the T-shirts cross country runners enjoy wearing — besides “our sport is your sport’s punishment” — are those that emphasize the importance of summer training.

“Summer miles bring fall smiles” and “Medals are earned in the summer and picked up in the fall” are among the favorites.

Marine City Cardinal Mooney senior Tyler Lenn wasn’t smiling much during the summer, because he was unable to log those all-important miles required for building an aerobic base.

He ran through injuries during track & field season before the pain became too much. He was dealing with a stress fracture, Achilles’ tendinitis and calf strains in both legs.

“Mentally, for me, it was not where I wanted to be,” Lenn said. “I don’t think anybody would want to be in that position. At the same time, there’s nothing I could have really changed about it. I made the most out of the situation, and I guess I showed that today.”

Lenn was all smiles Saturday at Michigan International Speedway, standing atop the podium after winning the MHSAA Lower Peninsula Division 4 individual championship.

Lenn posted a personal-best time of 15:49.0 to win by 12 seconds over Owen Patton of Vestaburg.

It was the culmination of a rocky season that began to turn around Oct. 20 when he won his league meet in 16:02.1. He ran 18:35.1 17 days earlier and 17:09.3 in his previous meet.

“I was like, ‘OK, I feel like I have a little bit of confidence in my body again,’” Lenn said. “Throughout the season, it was really rough. I would just fall apart in some races where I would trip and tweak the ankle and I would fall apart in the race mentally.”

Patton held a slight lead at the mile and two mile before Lenn laid down the hammer in the final mile.

“I think I made the right move,” Lenn said. “I just fought for positioning in the first 400 (meters), kind of held myself back a little bit to save for the end.”

Top-ranked Hillsdale Academy won the team championship, scoring 129 points to win by 70 ahead of Holland Calvary. It was the second MHSAA championship for Hillsdale Academy, which won in 2021.

Senior Thomas Holm was fourth, junior Reece Poole was fifth, sophomore Grayson Rorick was 20th, freshman Ryan Miller was 76th and sophomore Harry Lindsley was 80th for Hillsdale Academy.
