This week's Good Media Idea features a shoe brand, Asics, and their promotion of the NY Marathon last weekend. Their idea falls in the "Alternative Media" category for Media Life Magazine, and those are the types of media ideas we like. Here's the premise: A treadmill sponsored by Asics, is driven around New York City on a flatbed truck; it's preset to the record speed of an Olympian runner, Ryan Hall and folks on the street can strap in (there's a special harness hung overhead) and try to keep up to his 4:46/ mile pace. This is all to promote the NYC marathon. It's part event marketing, part PR-stunt, part creative out-of-home campaign, and ALL buzz worthy. We like it.
