Dolores Checa, well, she's one of the top Europeans so she's tested all the time, universal testing at Daegu wouldn't make any difference. The biological passport is something she'll have to sign up to now or later so that makes no difference either. Daegu isn't the one and only chance for the passport, the IAAF could use the last blood sample they took or one from the next meet she runs.
She's peaked for the season. Here are her 5k times on the IAAF list:
14:46.30 09/06/2011
14:46.89 08/07/2011
15:02.24 29/07/2011
