competitions like this. It'd be a fairly quick way of getting it back to
real racing and honesty.
Drugs testing is an arms race. Drugs (and other performance enhancing
techniques, like autologous reinfusion) get developed before tests for
them do. So there will always be drugs for which there are no tests yet -
and drugs which are not banned yet.
EPO, for example, which is the drug of choice for endurance athletes,
currently doesn't have a reliable test. There is a test, developed by the
same French lab which carried out the Landis tests last year, but it is
difficult to carry out and appears to suffer from false positives (e.g.
the case of Rutger Beke). At present there is no accepted way of detecting
autologous reinfusions.
The blood stored by Eufemio Fuentes appears to have been intended for
autologous reinfusion. Ivan Basso claims that he had blood stored, but had
never reinfused any. There is absolutely no way of proving this either way
(except through a systematic audit of Fuentes' records, if they exist and
if we believe them), because the blood was his own in the first place.
So - you could test all the cyclists in the peloton for all the drugs for
which reliable tests exist, and you still wouldn't catch the ones using
EPO, or autologous reinfusion, or a variety of other things. Meantime, if
you included tests for things like EPO, you would end the careers of a
number of perfectly innocent people.
Many things a rider may use are eliminated from the body in the course of a
single day. Most of the things a rider may use are hormones and chemicals
which exist naturally in the body, so just finding them doesn't prove
they're injected - and, in the particular case of testosterone, varies
widely in level from one individual to another. Which is why the tests for
these things are not tests to see whether they're there, but tests to
check the ratio between one thing and its biological precursors and
successors - and these tests are often very delicate and very hard to
interpret, as the Landis case shows.
