French judo athlete Teddy Riner, a 6-foot-8, two-time gold medalist known as "Big Ted," has dominated his sport for a decade. It was a shock when he lost in a quarterfinal fight.

Rafaela Silva grew up in a favela known as the "City of God," about 5 miles from where the competition took place in Rio. She and her sister took up judo to defend themselves and stay out of trouble.
