ROSEBURG, Ore. -- A student at Green Elementary School in Roseburg is taking recess to the next level by running more than 30 miles.
Lap after lap, third grader Mateo Rivero has ran 32 miles in less than three months after the school started a running program called Green on the Run.
"I felt really happy and proud of myself," said Mateo.
Teachers track the students' progress by scanning their cards each time they complete a lap.
So far, they've ran more than 900 miles combined.
"They love PE they love to run," said Green PE teacher Jamie Hummel. "They love to move, and to see their name and know how many miles is the biggest motivation for them."
Students don't have to participate.
Hummel says the program teaches kids how to pick a healthy lifestyle early on.
"This is teaching them a lifestyle because they do sit a lot in class, ya know? And rightfully so; they have to learn. But this is that option to go and run."
Students are then placed in a 5K, 10K, half-marathon or marathon club.
Mateo is the only student so far to reach "Marathon Club" status, and he's not done yet; he says he wants to run 100 miles by the end of the school year.
School officials hope Mateo inspires other students to exercise while having some fun along the way.
