Thanks for posting the list - most of the people had less than 4 tests, many just 1 or 2. The rational would be interesting to know. Are you tested more if you set an AR? Qualify for a championship? Win a championship? It's just strange, there seems to be a real trend (but not a rule) toward heavier testing of: Distance runners who train or recently trained in Oregon.
Brief collection of the more tested athletes below:
Abdihakim M Abdirahman 14
Fernando Cabada 16
Matthew Centrowitz 14
Mebrahtom R Keflezighi 18
Kara Goucher 15
Matthew Tegenkamp 17
Nick Symmonds 15
Dathan J Ritzenhein 21
Lopez Lomong 18
Galen G Rupp 28
Shalane G Flanagan 20
Here's a strange one though. A 39 year old who is still the best 3000-5000 meter runner in the US, one of the top in the world, setting AR's with a questionable test result from the past, and yet tested less than Lomong, Teg, Ritz, Meb, Shalane and Rupp.
Bernard Lagat 15
And here some the are even less, that I would have thought should have been tested much more. Not sure if it was because they were injured, or USADA didn't want to risk testing too often for fear of what they may find!
