A 23-year-old man training at ESPN Wide World of Sports Complex at Disney World is hoping to be the first American to compete both in the Paralympic and Olympic games.
"I had no idea how fast I would end up being. I came home with two medals at the last Paralympic Games," Blake Leeper said. "I got a silver medal in the 400 and a bronze medal in the 200."
Leeper was born without his lower legs. He was fitted with his first pair of prosthetic limbs at just 9 months old.
"I remember being young, growing up and wondering, 'Why am I here?' In the area that I grew up in, I was the only kid missing his legs," the Tennessee native said.
But those thoughts didn't last long. His family served as his motivation, and Leeper wanted to be just like his older brother, Kris.
"Everything he did, I had to do. I didn't really think about my disability. I never really thought about missing my legs," Leeper said.
Said his mom, Edith: "We wanted him to be independent and be able to survive. We got a plan together. Just treat him as normal, just like our oldest kid."
Leeper's dad coached young Blake and Kris in basketball, baseball and football.
Three years ago, Leeper took a go at track.
"When I got my running legs, the first thing I did was go challenge [Kris] to a race. I beat him three times," Leeper said.
He wants to finish a 400-meter race in 46 seconds to go to the 2016 Olympic Games in Rio de Janeiro. His current time is 49.7 seconds.
"For a sprinter, it takes about six to seven years to develop those muscles on a professional level," he said.
But he isn't discouraged. He said he has learned better than that.
"I feel like track has came in to my life and came in to my path, and it is my duty to go around and inspire people all around the world and people who experience the same thing I experience, who question why they are here in life," Leeper said.
"In the real world, everybody has excuses. It is just how you overcome them."
