Valentina Petrillo fell in love with athletics as a seven-year-old while watching Italian sprinter Pietro Mennea win gold in the 200 meters at the 1980 Moscow Olympics. Four decades later, at 50, Petrillo is about to finally realize her dream, but not at the Olympics. In two weeks, she is set to become the first transgender woman to compete at the Paralympics when she runs the 200 and 400 meters in the T12 classification for visually impaired athletes in Paris.
