I must not be the right audience for this ad. If I didn't know it advance it was Nike, I never would have figured it out until the end, but I would have stopped watching it before the end. It seemed very chaotic to me, and I am not sure what the message was.
Well, I signed up, and it's not free. But it is still very cool. You order this sport band and chip for $59, and plug it into your computer after a run and it uploads all your data to the site. Although it's not free, I still see how this can be a big appeal for runners, especially since self-monitoring is such a big part of the sport.
