She also participated in fencing practices with local children while getting instructions from Olympian Ibtihaj Muhammad. She also passed basketball alongside three-time Olympian Tamika Catchings and other members of the US women's basketball team.

"Our goal is the gold, every time," Catchings said. The 36-year-old Indiana Fever forward will be the oldest US player ever in Olympic women's basketball when she goes to her fourth Olympic games in Rio.

"100 days seem quite a long time, but we have to get back to the ground of training and stay focused," said Catchings.
