Rebook is offering runners the chance to win a pair of Reebok ZPump Fusion shoes by traveling through the streets of San Francisco on Instagram, in what agency Venables, Bell & Partners is calling the "first-ever Instagram-based virtual run."
Players begin the game at a specially designed Instagram account, which acts as the start line. Next, users can search the account's grid of photographs for the Pump ball logo, which is hidden within the images. Once it's been found, users simply like the photo and click the associated tag to the next Instagram account, continuing the "run." If they reach the finish line at the Golden Gate Bridge, they can enter a draw to win a pair of new Reebok ZPump Fusion. The game continues until May 11.
