Emma Green Tregaro of Sweden competed in this morning's qualification rounds in the World Athletics Championships in Moscow.
But what caught everyone's attention was her rainbow nail art on both hands.
She revealed her plans to compete with the rainbow nails via Twitter, adding "#pride."
Tregaro says of her silent protest against Russia's anti-gay laws:
Her decision inspired Swedish sprinter Moa Hjelmer to do the same.
Hjelmer told Swedish Radio:
Russian pole vaulter Yelena Isinbayeva spoke out against the Swedish athlete's actions.
At a press conference, she said:
"It's unrespectful to our country, it's unrespectful to our citizens. Because we are Russians, maybe we are different from European people, maybe we are different to people from other lands, but we have our laws that everyone has to respect [...] If we will allow to promote, do all this stuff on the streets we are very afraid about our nation. We consider ourselves normal standard people, with boys with women, women with boys. Everything was fine, this comes from history. We've never had these problems in Russia and we don't want to have it in the future"
