Ida Keeling has set a record as America's oldest sprinter. The Bronx athlete started running when she was already a senior, at 67. Her training regimen includes lifting weights, riding a stationary bike, and running the halls of her apartment building at home.

"Sometimes, before I run, I feel like maybe I'm too tired," Ida said.

But that doesn't stop the 97-year-old from competing.

Watch Ida break the record for fastest 100 meter sprint in the 90-years-and-above age group.
