CHASING SHADOWS

For anyone well-versed in video gaming, ghost challenges will be familiar. In short, you challenge a visual representation of your previous best – a bit like your Strava PB coming to life and trouncing you on your Sunday run.

Some VR apps like HOLOFIT already offer this function and now, with Apple’s augmented reality glasses just around the corner, it may not be long before this function moves beyond VR into the real world and you find yourself literally haring after yourself.
