A transgender high school track athlete in Alaska made history – and created controversy – after competing in the girls' state meet championships.

Anchorage CBS affiliate KTVA-TV reported that Nattaphon Wangyot of Haines High School qualified for the girls 1-2-3A 11-meter and 200-meter finals. The 18-year-old runner was born male and identifies as female.

Wangyot, who move from Thailand to Haines in 2014, told the Chilkat Valley News that she doesn't have a competitive advantage over other girls because she takes female hormones and other drugs to suppress her body's testosterone.

"The people who are going to think, 'It's not fair to play with the boys' – well, you don't know that. It's not easy," she told the Valley News. "It's not like I was up and 'OK, I'm a girl right now.'"

Saskia Harrison of Hutchison High School in Fairbanks, who missed the cut, didn't think it was competitively fair that Wangyot competed on the girls side.
