Tramadol use in the peloton was pretty rife (4% of tested samples), and was banned by the UCI due to safety concerns – riders may lose concentration. Out of competition, it is still allowed. Quintana’s team must have known this, but perhaps misunderstood “competition” to mean just during the daily race rather than at any time in the three week.
Tramadol has a relatively short half-life (6h) and it’s notable that’s it’s a blood sample (often rest day samples). This was a Dried blood spot from 8/13 apparently – we’ve tested dried blood on occasion but not used it for quantitation, but as a presence/absence it has its use. Will have needed at least a day to be eliminated.
First offence is disqualification, second is a five month ban, further offences are nine month ban. A UCI team with more than one positive in a year there’s a fine and then a ban.
