When it comes to the athletic movement there are boundaries that seemed impossible, until 1954 the four-minute mile was perceived as unbreachable, until runner Roger Bannister shattered this time limit on a blustery Oxford day.

The Wire’s Thomas Koutis asked Associate Lecturer Kyle Pringle from the University of South Queensland University about the significance of breaking the two hour marathon time barrier.
