Olympic gold medalist Florence "Flo-Jo" Griffith Joyner died 25 years ago on Sept. 21, 1998. The sprinter's world records for the 100 meter and 200 meter events remain unbroken.

David Brown already has one Paralympic medal under his belt. He and sighted guide Moray Steward hope to sprint their way to another in Tokyo.

The two coaches had their credentials revoked by the International Olympic Committee four days after they ordered sprinter Kristina Timanovskaya back home for publicly criticizing them.
