"At the Olympic Games, even the smallest margins can be the difference between victory and defeat. So, it is absolutely clear that it would not be fair for biological males to compete in the female category."
The Italian biathlete Rebecca Passler rejoined her team at the Winter Olympics on Monday after a successful appeal against a suspension handed out before the Milano Cortina Games for an alleged doping violation. Passler began training in the bright sunshine at the Antholz-Anterselva Biathlon Arena on Monday afternoon, firing off shots in bunches of five on the range as her coaches watched intently.
But there's also the matter of making sure one's equipment is up to snuff - and, beginning with this year's Winter Olympics, that means not having any PFAS, or "forever chemicals," in the mix. What happens if a competitor does turn out to have such chemicals in their equipment? They'll find themselves disqualified. As GearJunkie's Mary Andino reports, three skiiers have been disqualified so far due to their use of fluorocarbon wax, also known as "fluoro wax."
