Cycling Anti-Doping Federation Expresses “concern” Over Blood Data Leaks

The world of athletics has been rocked in recent weeks by the publication of leaked blood test data 1that is said to reveal widespread doping in the sport and it has raised concerns in cycling too.

The Sunday Times, along with Germany s ARD/WDR broadcaster, published data drawn from 5,000 IAAF (International Association of Athletics Federations) athletes, which they said revealed a vast amount of cheating in the sport. They allege that many of these suspect results were never properly investigated. The newspaper had experts examine the files, which were drawn from tests ranging from 2001 to 2012, and said that over 800, or one in seven, athletes named had blood tests that were suggestive of doping. Ten medals at the London 2012 Olympics were won by athletes with suspect test results, it said. Parallels were immediately drawn with Armstrong-era cycling, when the UCI failed to follow up on evidence that top riders were using performance-enhancing substances2.

Cycling Anti-Doping Foundation (CADF) Director Francesca Rossi told Cycling Weekly, In general, leaks are a concern in anti-doping, not only for the Athlete Biological Passport programme, but for any activity, from strategy to direct Anti-doping Rule Violation. Cycling uses the same Anti-Doping Administrative Management System (ADAMS) as athletics. WADA said this week that the leak did not originate from the system, which it refers to as a clearing-house where all data can be stored .

We ve never lost sight of the need to prevent leaks, as they can t be totally avoided, Rossi continued. We use a protected and specific web platform to share files and information.

Rossi outlined a system of ever-changing passwords, records passed only by USB sticks instead of e-mails, and cyclists IDs that expire with time.

The governing body, the UCI4, does not have access to the system, and the records are restricted to a select few at the foundation, Rossi said. WADA has criticised the recent publication of the leaked data, but has announced an urgent investigation. Those in the cycling anti-doping body are sceptical about the ability of outsiders to interpret the complex data surrounding blood testing.

The biological passport software is a very complex statistical tool able to make a preliminary and rough interpretation of each passport. This complex procedure should indicate that any superficial approach made by not-qualified people can lead to a misinterpretation of a passport, Rossi said.

One abnormal value does not amount to rule violation.

It is the variations between the values which can be an indirect proof of doping.

A single value can only be used to perform target testing or target analysis on the blood sample.
