Jack has remained silent on the Chinese doping news because she doesn’t want it to impact her preparation for Paris.
“For now, I’m just focusing on my dream and not letting anything crush that,” Jack told this masthead on the final day of Australia’s Olympic and Paralympic trials in Brisbane on Saturday. “To be honest, I’ve tried to put it on the back burner for now.
“My focus has been on the Olympics and getting through the trials and through to the Olympics. I really appreciate there’s been a lot of people who have reached out and wanted to know my thoughts and my opinion, but I’ll definitely be commenting on it after the Olympics.”
Stubblety-Cook addressed the China issue last week at a press conference.
“It does affect me and it affects a lot of other athletes as well, including [members of the Australia’s women’s] 4x200 relay,” Stubblety-Cook said. “For me personally, it’s something I’ve had to kind of go, well, this sucks, but what can I do about it? I have to have faith in the WADA [World Anti-Doping Agency] system.”
Ahead of the US trials next week, American star Lilly King was asked about news of an extra three Chinese positive tests.
“It’s really frustrating for athletes to always have in the back of our mind that maybe this sport’s not fair,” King said. “We put everything on the line. Our privacy, everything that we do to compete on a level playing field. It’s really frustrating to not have faith that others are doing the same thing.”
