Chinese track cyclist Junhong Lin, a four-time world championships medalist, has accepted a four-year ban after anti-doping authorities retested samples collected nearly a decade ago, the International Testing Agency \u00a0said Wednesday.<\/p>\n
The doping case dates back to urine samples collected during the UCI Track World Cup in Hong Kong and the Asian Track Championships in Izu, Japan, in 2016.<\/p>\n
The samples were stored and later reanalyzed as part of the UCI\u2019s long-term testing program, which allows old samples to undergo fresh testing using the latest detection methods.<\/p>\n
She tested positive in two samples for the exogenous origin of adiols, an anabolic steroids banned at all times under the World Anti-Doping Agency code because of its muscle-building and performance-enhancing effects, the ITA said.<\/p>\n
Lin, who won four medals in sprint events at the track world championships, did not contest the charges and accepted the sanctions.<\/p>\n
Her suspension runs from October 7, 2025, through October 6, 2029.<\/p>\n
The ruling also wipes out all of Lin\u2019s results from January 16, 2016, the date of the first positive sample, until the start of her provisional suspension in October 2025.<\/p>\n
Latest bust in back-testing program<\/h2>\n
The case is the latest high-profile sanction to emerge from cycling\u2019s long-term sample storage program.<\/p>\n
Under WADA rules, blood and urine samples can be kept for up to 10 years and retested as detection methods improve.<\/p>\n
Some of cycling\u2019s biggest doping cases have emerged from retests. In 2008, Stefan Schumacher, Bernhard Kohl, and Leonardo Piepoli were banned after back-testing of Tour de France samples confirmed CERA positives. And retesting cost Davide Rebellin his silver medal from the 2008 Beijing Olympic Games.<\/p>\n
This latest case comes after the Tour de France was marked by an unprecedented wave of overnight controls by ITA, which runs anti-doping for the UCI.<\/p>\n
Riders including Jonas Vingegaard, Tadej Poga\u010dar, and Remco Evenepoel were subjected late-hour tests as the ITA intensified its \u201canytime, anywhere\u201d strategy. Every rider was tested during a peloton-wide rest-day control as well.<\/p>\n
ITA officials said many of those Tour controls will be incorporated into the biological passport program.<\/p>\n
The controls, combined with the long-term storage and retesting of samples, reveal how anti-doping authorities continue to expand enforcement beyond traditional finish-line controls.<\/p>\n
The decision can be appealed to the Court of Arbitration for Sport.<\/p>\n<\/div>\n
