Aspiring runners have the chance to pit their skills against Commonwealth Games gold medallists in a virtual duel of speed. In anticipation of the Glasgow Games, a converted container on Auckland's Halsey Wharf has been turned into a state-of-the-art virtual running track where wannabe John Walkers or Allison Roes can try to beat international running legends. Contestants test their speed on the track where each performance is captured using a series of motion sensors and digital cameras.
