Two athletes, Roncer Kipkorir Konga of Kenya and Maryna Bekh-Romanchuck of Ukraine, have been suspended for doping, the Athletics Integrity Unit announced Tuesday. Bekh-Romanchuck will serve four years, while Konga will be sidelined for three years. Both tested positive for testosterone.
Maryna Bekh-Romanchuck
Bekh-Romanchuck specializes in the long jump and triple jump events.
On December 7, 2024, the 30-year-old provided a urine sample out-of-competition in Khmelnytskyi, Ukraine. In March, the World Anti-Doping-accredited lab in Lausanne, Switzerland, found that she tested positive for “5α-androstane-3α,17 diol (“5αAdiol”) and 5β-androstane-3α,17 diol (“5βAdiol”) consistent with exogenous origin (the “Adverse Analytical Finding”) following analysis by GC/C/IRMS.”

In May, she was contacted about her positive test. While she attempted to explain her positive test to the AIU regarding taking prescribed medications, she failed to defend her positive test convincingly. Her B sample test confirmed the A sample results.
She was then suspended for four years, and the results dating back to December 7, 2024, were removed.
Bekh-Romanchuck won silver medals, one each in the triple and long jump events at the 2023 Budapest and 2019 Doha World Athletics Championships. She finished fifth during the 2021 Tokyo Olympic Games.
Roncer Kipkorir Konga
On December 29, 2024, Roncer Kipkorir Konga provided a urine sample out of competition in Iten, Kenya. A month later the WADA-accredited laboratory in Lausanne reported that his sample was negative.
The sample was tested again on June 11, 2025. The lab then confirmed a positive test for testosterone or androsterone, 5αandrostane-3α,17 diol (“5αAdiol”) and 5β-androstane-3α,17 diol (“5βAdiol”), consistent with exogenous origin in the sample.
By July, having exhausted his excuses to do with a herbal medicine made by his mother and taking the supplement TestoXT, he admitted guilt and accepted the consequences handed down by the AIU. He will serve three years from June 16, 2025.
In 2023, Konga ran the half-marathon in a time of 59:08 in Buenos Aires. He has run at least three other sub-60-minute half-marathon events.
