Following yesterday's news that four Costa Rican riders have tested positive, the UCI has confirmed to VeloNation that the substance in question was indeed the banned substance GW501516, and has named the riders concerned.
"The UCI advised four Costa Rican riders in the first week of April 2013, Vargas Barrantes, Mudarra Segura, Morales Castillo and Villalobos Azofeifa that they were provisionally suspended," UCI Communications manager Devra Pitt Gétaz said today (...).
"The decision to provisionally suspend the riders was made in response to a report from the WADA accredited laboratory indicating an Adverse Analytical Finding of metabolite GW1516 sulfone - Metabolic Modulator in a urine sample collected from them in an in-competition test in December at the Vuelta Internacional a Costa Rica 2012."
Three of the riders are from the BCR Pizza Hut team. Paulo Vargas Barrantes took stages two and eleven in the Vuelta a Costa Rica, and also finished ninth overall. The 33 year old is a former Vuelta a Guatemala and national road race championship winner.
Allan Jose Morales Castillo is 24 and finished fourth overall in the 2012 race, the highest of the four riders. He also nabbed three top five stage finishes. In 2010 he was runner-up in the national road race championships.
Pablo Mudarra Segura took the national road race title last year and had six top ten stage placings in the Vuelta a Costa Rica, as well as taking eighth overall. He is the youngest of the quartet at just 21 years of age.
Steven Villalobos Azofeifa is from the Coronado squad. He previously tested positive for Clomifen in the 2009 Vuelta a Costa Rica, incurring a two year suspension. That ended on March 24 last year, and after finishing back in sixteenth place in the national championships, he improved his level for the Vuelta a Costa Rica, where he won stage twelve, picked up third on stage six and finished sixth overall. Now 26 years of age, he's facing a potential lifetime ban for a second offence.
Like the other three riders, he presumably must await the results of the B sample analysis.
Asked about rumours that two unnamed Colombian riders had also returned positive A samples for GW501516, Devra Pitt Gétaz clarified that the UCI ‘has not opened any procedure against any Columbian riders for this substance.'
