A year and a half ago, a babysitter signed the girls up for a track meet as a no-cost way to keep them busy.
That day, coaches from Brooklyn's Jeuness Track Club were at the meet looking for new talent. Each sister got an invitation to join the team — and the scouts had no idea that they were sisters.
The sisters quickly rose to the top of the pack, qualifying for the Junior Olympics in multiple events.
At this very moment, the Sheppard sisters are in Houston, Texas, competing against the top junior runners in the country.
Rainn has already won her first event, the 3,000.
Unfortunately, their mother isn't there with them. She's unable to take time off work, and the shelter they live in has a strict curfew for its residents.
Until then, Tai, Rainn, and Brooke will keep training hard. "This is a means to get them to college," Handy told the Associated Press. "To opening doors that maybe I can't open for them."
