How fast can you run? A while ago, Reebok set up a cool billboard in Stockholm with a built-in speed camera that measured how fast pedestrians jogged (or ran) past it. Anyone who ran faster than 17 kilometres per hour (10.56 miles per hour) unlocked a pair of Reebok ZPumps. Watch the stunt in action below.

The agency is Animal, Stockholm. Seen a better campaign in this category of late? Share this post and voice your views in the comments below.
