A Disciplinary Tribunal has handed Kenyan athlete Hillary Kipchirchir Chepkwony a four-year ban following a doping violation linked to the Athlete Biological Passport (ABP) programme.

The ruling, comes amid continued global scrutiny of anti-doping compliance in athletics, also includes the disqualification of his competitive results dating back to August 2024.

“The Athlete is sanctioned with a period of Ineligibility for a period of four (4) years, until 7 December 2029, taking into account the Provisional Suspension served to date. All competitive results of the Athlete are Disqualified since 24 August 2024, and includes the forfeiture of any medals, titles, points, prize money and prizes since that date,” the ruling read.

The decision adds Chepkwony to a growing list of athletes sanctioned under biological passport-based evidence, a system designed to detect performance manipulation through long-term monitoring of blood markers.

Four-Year Ineligibility Sanction Issued

According to the AIU disciplinary decision, Hillary Kipchirchir Chepkwony has been suspended from competition for four years for violating anti-doping regulations linked to abnormal biological passport readings.

The period of ineligibility begins on 8 December 2025 and will run until December 7, 2029.



The ruling confirms that the athlete committed an Anti-Doping Rule Violation (ADRV) under the category of use of a prohibited substance or method.

Chepkwony is now barred from participating in any competitions, events, or activities sanctioned by World Athletics or its member federations during the suspension period.

Decision was issued following a review by the disciplinary tribunal, which evaluated biological data collected over time and the panel concluded that the abnormalities in the athlete’s profile were consistent with prohibited performance-enhancing methods.

In addition to the suspension, the tribunal ordered the disqualification of all results obtained by Chepkwony from 24 August 2024 onwards.

This includes the annulment of race placements, rankings, titles, and any prize money earned during that period.

Kibiwott Kandie Suspended for Alleged Doping

Kenyan distance runner has been formally charged by the Athletics Integrity Unit (AIU) in an anti-doping case involving alleged violations of doping control procedures.



 Kibiwott Kandie, is now facing additional allegations of tampering or attempted tampering with the doping control process, adding to an earlier charge related to evading or refusing sample collection.

The AIU confirmed that Kandie has been issued with a Notice of Charge that introduces a new allegation of tampering or attempted tampering with doping control. 

Tampering charges relate to potential use of prohibited substances and also interference with the testing process itself.

If proven, such violations carry severe sanctions, including long-term bans from competition.

Before the latest charge, Kandie was already under investigation for allegedly evading, refusing, or failing to submit to sample collection.

Under World Athletics rules, athletes are required to submit to sample collection without obstruction when notified. Failure to do so is treated as a serious breach, even in the absence of a confirmed positive test result.
