One year ago, 16-year-old Matt Lopez never dreamed he'd be running the ten mile race.
He said he was sluggish and overweight - and wanted to change.
"I didn't feel like I was living to my full potential," he said.
So he joined 'Students Run Philly Style.' It's a mentoring program that uses long distance running to transform young people's lives.
Matt lost 50 pounds - and improved his grades at school.
"Now I am bringing home A's and it makes me feel really good about myself," Matt said.
He's also bringing home healthy habits. He and his mom are now eating healthier -more lean protein and veggies. His mom is also working out and has lost 20 pounds.
"I have more to go but I have my personal trainer here and I am very proud of him," she said.
Heather McDaniel, the founder of Students Run Philly Style, says running is the ultimate confidence booster - which can help point kids down a path of success.
"I think running is self-proving. He owns every mile he put in and when he gets that medal, he did it all himself," Heather said.
"I like who I am better, not just with weight. It changes your life overall," Matt said.
Matt also credits his high school - Cristo Rey- for his success.
He says he is a bit nervous but excited for the Broad Street Run next weekend.
