OregonGoldRush | Kenya's Cherono, USA's Ross provisionally suspended by AIU for anti-doping violations

Kenya’s marathon runner Lawrence Cherono and American quarter-miler Randolph Ross have been provisionally suspended by the Athletics Integrity Unit (AIU) on Saturday. It means both athletes are out of the World Athletics Championships in Eugene, Oregon.

Lawrence tested positive for trimetazidine, a substance on the World Anti-Doping Agency's (WADA) banned list for 2022 as a metabolic modulator.

Substances in this category modify how the body metabolises fat. Trimetazidine is approved for use in some countries to treat chest pain stemming from a lack of blood supply and oxygen to the heart.

Trimetazidine is a non-specified substance, and a provisional suspension is mandatory after an adverse analytical finding for such a substance under the World Athletics Anti-Doping Rules unless certain conditions apply.

Cherono’s sample was collected by the AIU during an out-of-competition test on May 23. The WADA-accredited laboratory in Lausanne, Switzerland that analysed the sample, received it on May 27, and notified the AIU of the adverse analytical finding on Wednesday.

He was travelling to Eugene at this time and was notified of the adverse analytical finding when he arrived in Eugene on Thursday. In accordance with the Rules, the athlete was provided with an opportunity to show cause to the AIU why he should not be provisionally suspended.

Having considered the submission of Cherono, received late on Friday, the AIU has determined that a provisional suspension should apply with immediate effect and Cherono will not take part in the marathon on Sunday.

The AIU said that under the WADA International Standard for Laboratories, reporting of sample results should occur within 20 days of receipt of the sample. In this case, the delay to the time of reporting was 47 days. The AIU has made a formal complaint to the laboratory in relation to this unacceptable delay, which has denied the opportunity for another Kenyan athlete to take the place of Cherono in the marathon.

Meanwhile, Ross has been issued a Notice of Allegation by the AIU alleging a violation of Rule 2.5 of WADA Rules for tampering with the doping control process. The allegation arises out of the athlete’s conduct during the course of an investigation into a potential whereabouts violation.

There was an unsuccessful attempt by the AIU to test Ross on June 18 and the investigation into this matter concluded when Ross was interviewed by the AIU in Eugene on Thursday.

The AIU has imposed a provisional suspension on Ross with immediate effect and he will not take part in the 400m heats on Sunday.
