British former Tour de France cyclist Robert Millar has completed a transition to become a woman.
The 58-year-old has decided to go public with the gender change because she says there is "a much better acceptance and understanding".
Millar was best known for winning the King of the Mountains prize in the Tour de France in 1984.
Philippa York, who becomes the first high-profile cyclist to go public, made the statement on cyclingnews.com.
York, who says she has been going through the transition since 2000, added: "The outcome of that journey has meant that for a considerable time now I have lived as Philippa."
"The steps taken over a prolonged period under the watchful eye of the medical profession to complete the transition from one gender to another can be difficult and are always only taken after much soul searching and anguish," she added.
The Scot is now part of ITV4's commentary team for the Tour de France, which runs until 23 July.
