History-making female jockey 'completely shocked' after positive test for cocaine

A trailblazing female jockey has been left "completely shocked" after testing positive for cocaine. Sibylle Vogt, who is Swiss-born but is based in Germany where she works for Arc-winning trainer Peter Schiergen, became the first woman to ride a Classic winner when capturing the German 1,000 Guineas on Novemba in 2021.

In the 2025 season she has ridden 17 winners which has put her third in the German Flat jockeys’ championship. But her campaign has been upended by the results of a routine drug test taken while she was riding at Compiegne in France in March this year.

According to the , a sample taken from Vogt tested positive for cocaine. The result of a test of a B sample has yet to be confirmed. Vogt, who has ridden 371 winners, was last week picked for the Europe team due to ride at the Dubai Duty Free Shergar Cup meeting at Ascot in August.

She said: "The news has completely shocked me. I can't, for the life of me, explain how this outcome could have come about. Throughout my entire career—and beyond—I have never had contact with drugs or other illegal substances.

"I don't suffer from any weight problems and am very satisfied with my current professional situation at the Asterblüte stable."

She continued: "I'm currently doing great in terms of sports, and there's no reason to distract myself in any way. I celebrated my 30th birthday a week before, on March 23rd – it was a lovely, carefree evening in private. Neither I nor my guests nor my family had any contact with drugs.

“I take this matter extremely seriously, immediately had voluntary tests conducted, and am working transparently with the relevant authorities in France and Germany.

“I have hired a French lawyer to clarify the legal situation and sincerely hope that this nightmare will soon be resolved."

Schiergen, who trained Danedream to win the Prix de l’Arc de Triomphe in 2011, said he was right behind Vogt.

"The news came completely unexpectedly,” he said. “Everything has been going very well recently. Sibylle has made it clear to me that she has had no contact with cocaine. Now we need to stick together as a team, wait and see, and support her as best we can."
