Indian sprinter Dutee Chand won on her return to the track following a successful appeal against a ban imposed after a so-called gender test.
The 19-year-old took 100m gold at the National Open Athletics Championships in Salt Lake, India, in 11.68 seconds.
Chand was banned under athletics' hyperandrogenism policy, which found she had naturally high levels of testosterone above a permissible level.
She successfully appealed at the Court of Arbitration for Sport in July.

"I was under pressure, coming into this event - a little nervous as well," she said after the win, which was a fraction outside her personal best.
"I didn't perform at my peak, for I knew I could get better.
"But this win will give me the confidence and now I can write to the sports ministry, requesting them to get me into the Target Olympic Podium (TOP) scheme for the 2016 Rio Olympics."
