Marketing Energy Burn To Sell Energy Bars

In July, Clif Bar hosts the Clif Kid Game of the Year contest, which asks kiddies to get active by inventing backyard games. General Mills brand Nature Valley gives adults a similar nudge with its Trail View website, where couch potatoes watch pedestrian-level views of hiking paths in our national parks (and hopefully get inspired to literally take a hike).

We crunched the numbers.
