PARK CITY, Utah — The protesting of racism and police brutality by American athletes started with W.N.B.A. players at a news conference in July 2016 and soon spread to the playing fields of the N.F.L. and the hardwood courts of the N.B.A. In less than five months, the Winter Games in Pyeongchang, South Korea, will present a far larger stage for demonstration: an Olympic podium.
Kehri Jones, an Olympic hopeful in bobsledding, was among those at an athlete summit here this week who said that athlete activism was something she had been thinking about and discussing with teammates as the Pyeongchang Games approach.
