Champion cyclist Jack Bobridge was sentenced for four years and six months for the offences with the judge saying the Olympian's dramatic fall from grace was an "absolute tragedy".
The Adelaide-born father-of-one maintains his innocence, but a WA District Court jury found him guilty of supplying ecstasy tablets in 2017 to former professional cyclist Alex McGregor.
Bobridge, an Olympic and Commonwealth Games medallist, supplied the drugs months after he retired from the sport suffering rheumatoid arthritis.
Defence counsel Sam Vandongen said his client had indulged in alcohol and drugs while enjoying celebrity status in Europe and it was remarkable he had been able to train.
"They are treated as superstars," Mr Vandongen said on Friday.
