Several current Olympians on the 2016 United States of America team have publicly witnessed to their Catholic faith while in Rio de Janeiro. Three of the most prominent are gymnast Simon Boles, swimmer Katie Ledecky, and fencer Katharine Holmes. There are many recent news reports detailing aspects of their life as practicing Catholics. One story with several links is posted here.
At the conclusion of his August 3 public audience, Pope Francis shared these words to Olympians: “In a world thirsting for peace, tolerance, and reconciliation, I hope that the spirit of the Olympic Games inspires all – participants and spectators – to ‘fight the good fight’ and finish the race together (cf. 2 Tim 4,7-8), desiring to obtain as a prize, not a medal, but something much more precious: the construction of a civilization in which solidarity reigns and is based upon the recognition that we are all members of the same human family, regardless of the differences of culture, skin color, or religion,” the Pope said.
