Chinese track sprinter Junhong Lin, 35, has accepted a four-year ban after samples she provided nearly a decade ago were found to contain anabolic androgenic steroids, the International Testing Agency (ITA) confirmed this week.
The case stems from two in-competition samples Lin provided on 16 January 2016 and 29 January 2016 at the UCI Track World Cup III in Hong Kong and the Asian Track and Para-Cycling Championships in Izu, Japan. Both were later found to contain adiols of exogenous origin, a Class S1.1 substance prohibited at all times under the WADA Prohibited List because of its muscle-building and strength-enhancing effects.
The findings emerged after the ITA reanalysed the stored samples under its long-term testing programme, which allows older samples to be re-examined as detection technology advances. Lin did not challenge the findings and accepted the sanction without a hearing.
Her ban runs from 7 October 2025 to 6 October 2029. All of her individual results from 16 January 2016 onwards, including those from the 2016 Hong Kong World Cup and the Izu championships, have been disqualified.
Lin’s case adds to the growing list of cycling doping violations uncovered years after the fact, underscoring how the ITA’s retesting programme continues to reshape results long after athletes have left the sport. The decision remains open to appeal before the Court of Arbitration for Sport.
