My mind doesn't boggle at all.
Some people take amateur sport very seriously indeed. They make huge sacrifices of time, they spend all their available cash (and probably some unavailable cash) on super duper kit. Why should the attitude to doping not trickle down from the pro level? By not boggling I'm not saying I approve just that it's not terribly surprising.
"The anti-doping body then, after being handed information from an unnamed source, carried out further tests on the sample"
That it took a tip-off to trigger EPO tests (If I've understood correctly) suggests that the testing protocols are less stringent, which may affect a would-be doper's risk/benefit assessment.
