Among the dozens of athletes hoping to leap, throw or run their way to London as part of the U.S. track and field team is 24-year-old runner Shannon Leinert.

Leinert, who will compete in the 800-meter dash, has dreamed of the Olympics since she was 10 and winning races in St. Louis, her hometown. If that weren't enough, she's also working on a doctoral degree in special education.
