Velocentric said:$2000 to get to the Canary Islands? Maybe if you fly Air Lance. Regular flights cost no where near that amount from Europe (best I've found to Gran Canaria is £29 - approx $42 - each way).
I think you'll find that Teams use of the Canary Islands has more to do with the consistent climate, the relatively low cost of high class accommodation and the many, many miles of very well maintained roads and fantastic sporting facilities.
But hey, you could be right. It could be all about the $
$42 x 2 (you want to get back to the mainland right?) = $84. Throw in tax, and you got $130. Now throw in hotel, which gets you to $300. But how do you get to the hotel? Well, you rent a car. So now you're up to $500. Then you gotta pay the tester all that extra time, so add another $200 for that and you're up to $700.
Then you gotta fly the sample back refrigerated. How often does FedEx or a major freight carrier fly in or out of the Canary Islands? That's gotta be a $100 premium shipping charge easy. So now you're up to $800.
Then you gotta take into account that it might take the entire day to find Contador or wait for him to come back from his 6 hour training ride (or his 2-hour gynecologist appointment in the hotel room next door). So that means the tester has to stay an extra day, which means double the hotel and rental car fees.
So I can easily see the estimated average cost approaching $1,500 - and that includes the super-discount airfare you quoted which may not be available on short notice when WADA targets its OCC testing.
Given WADA's limited budget, they generally don't fly their testers to exotic locations around the world, as doing so would deplete their allocated budget. But since athletes appear to be strategically using these "training camps" to Mexico, the Canary islands, or the Swiss Alps to specifically bank on testers not showing up....
