Nike runs with the resolution crowd

We’re playing a bit of catch-up here in pointing you to this Nike Plus spot featuring Maria Sharapova challenging LeBron James to an athletic endurance challenge—it’s a New Year’s resolution thing. (Sharapova promises to run further than James in January.) Nike Plus, in case you’ve been spending too much time on the couch, is the Nike + iPod joint branded thing-a-ma-hoo that uses iPod technology to keep track of how far and fast you’re running and promises you jammin’ tunes to do it with.
