A 42-year-old US amateur cyclist has been handed a four-year ban after testing positive for five banned substances.

Cat 3 racer, Michel Carrillo, was tested as part of the RaceClean Program which focuses on amateur events.

“All athletes deserve a level playing field so that hard work and talent alone determine the outcome at every level of competition,” said US Anti-Doping Agency (Usada) CEO Travis Tygart. “USA Cycling’s RaceClean initiative and others like it help ensure that athletes know how to compete clean and that those who choose to use powerful performance-enhancing substances to gain an advantage are held accountable.”

Carrillo gave an in-competition urine sample at the Vuelta a Miami on July 29, 2018.

He tested positive for recombinant human erythropoietin (EPO), androgenic-anabolic steroids (AAS), 19‐norandrosterone (19‐NA) and the clostebol metabolite 4-chloro-4-androstan-3a-ol-17-one and testosterone metabolites.

All substances are prohibited at all times under the World Anti-Doping Code.

Carrillo’s four-year ban began on September 5, 2018, the date his provisional suspension was imposed. He also loses all competitive results and prizes obtained on and subsequent to July 29, the date his positive sample was collected.

Earlier this month, a 90-year-old cyclist who set a world record at the US Masters Track National Championships accepted a public warning after Usada accepted that a positive dope test was “more likely than not caused by contaminated meat consumed the evening before competing.”

Carl Grove said that anti-doping authorities were “wasting their time” targeting older athletes.
