Runners in the past weekend's Shanghai marathon are taking home a unique personalised souvenir of their run. 。

The 30,000 runners have been invited to plug in their run data from the event into a platform that will produce a 3D visualisation of how they performed. 。

The colourful chart can be panned in 360 degrees on a mobile phone with WebGL, and will reflect how fast each runner went over different stretches of the race. 。

The platform is the brainchild of ad agency Wieden Kennedy Shanghai, who produced it for BMW. It will accept data from popular Chinese fitness apps CoDoon, JoyRun, and Rejoice. Here's an example of what runners will get on their phones. 。
