He can run, but what does Australian track star, Peter Bol have to hide? After being sensationally suspended for a positive drug test earlier this year, it's the question the 800m champion finally answers on 7NEWS Spotlight. 

Back in January, the headlines screamed his guilt the world over, while Athletics Australia reluctantly forced their pin-up boy to quit all competition and training after receiving the anti-doping agency, Sports Integrity Australia, result.

His crime? Unusually high levels of synthetic erythropoietin, or EPO, in a urine sample.

The drug? The same banned blood booster used by disgraced American cyclist Lance Armstrong and a string of track and field stars whose reputations now lie in ruins.

Defiant in his denials, and determined to prove his innocence, Bol won a reprieve of sorts, when his B-sample testing was revealed this month – an ATF, atypical finding, neither positive or negative.

And so, the question lingers – is our national hero a drug cheat?

Now, in an explosive and exclusive interview with 7NEWS Spotlight host Michael Usher, the 29-year-old gets his chance to fight back; while his furious family unleash on the authorities who leaked Bol's original and damaging drug test result.
