This installation lets you know how much slower you are than an Olympian. With the press of a button, visitors can choose to “race” in the Men’s Olympic 100m, the Women’s Olympic Marathon, the Men’s Olympic 10,000m or the Women’s Paralympic T11 100m (a race for athletes with visual impairment). They then sprint along a 100m light trail on the footbridge to the Olympic Stadium that tracks the pace of different record-setting athletes. After the 2012 Games, the lights will be reset with the new winning times. The work, designed by the Jason Bruges Studio, also features an imaginary water surface on the underside of the bridge. Pedestrians taking the underpass will experience the speed of Olympic swimmers as lights glide overhead.
