The World Anti-Doping Association (WADA) has revealed that 736 requests for drugs tests of Russian athletes have been declined or cancelled during the country's period of non-compliance.
WADA gave a status update on Russian testing on Wednesday, just two days before the IAAF is set to reveal whether track and field athletes from the European nation will be permitted to compete in the Rio Olympic Games.
Russia's athletes were suspended from competition last November following allegations of state-sponsored doping in a report from WADA's independent commission.
The latest revelations from WADA included details of 111 'whereabouts' failures, 52 positive tests and 23 missed tests in the period from February 15 to May 29 this year.
WADA also revealed the extent to which athletes have gone to avoid being tested, with one seen running away from a notification area/mixed zone after competing and another unable to be found after exiting a stadium during her race.
It was also revealed that 15 athletes at the Russian National Walking Championship in February either did not start, withdrew from the event or were disqualified.
WADA also stated one female athlete used a container inserted inside her "presumably containing clean urine" and when she tried to use it, the contents leaked onto the floor rather than into the collection vessel.
She then allegedly tried to bribe a doping control officer (DCO), who retrieved the container which she had tried to throw away. The athlete in question later provided a sample with an adverse analytical finding.
WADA also gave details of DCOs being intimidated and federal security agents threatening DCOs with expulsion from the country.
