Simply terrific experiential mashup done by AKQA for Nike as part of their Run London effort, using Google Maps to produce a communal-based route-finder.
Searches can be done by criteria such as "Flat as Holland", "well-lit", Park versus road and of course by distance. Courses can be shared, printed, saved and even...run!
Nicely done! This is yet another smart way of demonstrating life after the 30-second spot!
