Jason dropped into the class looking for help marketing his company's iPhone App, RunKeeper, a GPS-based fitness application for runners and cyclists that we already reviewed here at Mashable. Their inspired idea: run the Boston marathon dressed as a giant iPhone with the RunKeeper app on the screen.
Being social-media savvy, the group posted a video of the whole process to YouTube (embedded below). The Boston marathon takes place Monday, and the group will post a final video of the run afterwards.
