StormTeam 5's David Brown is a regular runner. And he's noticed something – he has a lot of company out on the road. Tonight, he joins Chronicle for a look at why running is more popular than ever. He also meets a man who's mapped out the city's best routes, gets the lowdown on the health benefits of pounding the pavement, and goes to the research laboratory of New Balance to learn the latest on shoe technology.
