Nike GRID uses the now almost defunct iconic London telephone box to track a runner’s progress at designated Nike branded locations. After registering online, players run between two phoneboxes and punch in their unique user id number at each, logging their run and earning them points online. 

The more runs, the more points earned for that postcode. The person with the most points in each area claims the crown of that postcode, badges are also awarded for speed, stamina and insider knowledge of the streets. There are 40 postcodes in play and four phoneboxes in each, players are encouraged to use their street knowledge to get them around their local area as quickly as possible by any possible route.
