Nike Running is about more than just shoes: it's about encouragement. Benches with some clever alterations dissuade runners from taking a break and encourage them to keep running, in this smart campaign from F/Nazca Saatchi & Saatchi. Corra means "run" in Portuguese.

Update: Copyranterpoints out that the same idea was conceived by an NYC AD student, Anna Echiverri and her creative partner, Annie Chiu, more than three years ago. Echiverri, who now works at Arnold Boston, won a couple of awards for the concept work.
