Over the course of Olympic history, there have been plenty of LGBT athletes and coaches. Few, though, have attended the Games with their sexualities known openly. In 2008, only 12 out of 10,708 athletes were openly gay. There were just six in 2010.

Those numbers are changing with a record-breaking 40 openly LGBT athletes descending on Rio this summer. Team USA basketball star Elena Delle Donne came out as gay in a Vogue article leading up to the games. Get to know some of those pioneering Olympians as they look to make their marks on history.
