It wasn't the winners of the Corporate Cup that everyone was talking about Sunday, it was 13-year-old cross country phenomenon Seth Hirsch.

Hirsch showed off his warm-up routine to Channel Six, which includes twenty minutes of stretching and a brisk warm-up run. It’s not unusual for the teen to run eight or nine miles each day, but even he was surprised at the impressive finish.

He placed 10th out of 4,800 people who took part in the 10k race. And he did it in only 33 minutes and 50 seconds.

“I’d pass by the bigger groups and they'd be like good job,” says Hirsch. “Then a couple seconds after I'd hear them and they'd be like holy crap did you see that kid?”

Hirsch beat his personal best by over a minute and ten seconds. He says the remarkably fast time was due in part to the crowd cheering him on.

“At about the 4th mile I started really feeling it. In the 5th mile I was pretty much dead, but then the crowd picked me back up to finish it hard.”

Though Hirsch is proud of his finish, he says he hopes this isn't the only time he beats records.

“When I get taller and my legs get longer and I keep running hard I should be able to keep breaking some good records.”

Hirsch hopes to continue to compete in high school and even make it to the Olympics one day.
