Kamga was walking around the Stockholm stadium when a man in the stands started yelling at her.
The insults fly, he calls me the n-word and says I don't belong in the blue-and-yellow national team uniform, Kamga recounts in her summer talk.
The then 20-year-old became concerned about the man's aggressiveness.
Is this the moment I go down in public? I'm preparing myself for something worse than words to come soon.
The incident is reported to police and Kamga talks about it on her Instagram.
I am writing to make it clear - clear that racist attacks happen everywhere, she says.
The 27-year-old is at the European Championships in Birmingham and will qualify on Wednesday for the women's discus final.
