Sports science documentary Faster, Higher, Stronger sees journalist Ian O'Riordan examine how athletes are using science and technology to enhance their performance, asking whether or not we can ever again truly believe in the purity of sport.

The Olympic Games are meant to represent all that's good and pure about sport - heroic acts of courage, fair play, and being all that you can be.

But ever since Ben Johnson failed a drug test in 1988, the biggest sporting show on earth has been dogged by scandal and suspicion.

And now, with the curtain about to rise on London 2012, Ian O'Riordan of the Irish Times looks at the growing impact science and technology has on sport – legal and illegal – and wonders if sport can ever regain our trust.

A lifelong sports fanatic, Ian O'Riordan's world changed when Ben Johnson was caught at the 1988 Games.

Ever since, as a competitive distance runner, through his career as a sports journalist, he's been trying to answer the question that was raised that September morning in 1988 - is any of this real?

In Faster, Higher, Stronger, O’Riordan looks at a range of performance enhancement techniques, both legal and illegal, to discover if science has become more important than good old-fashioned hard graft and talent.

He also spends time with members of the Irish Olympic team for 2012, to get inside the mind of the people that go to extraordinary lengths to gain a competitive edge.
