Sorry, there are no airings at this time. Please check this page for future updates.

Episode 4 of "City Walk" begins with a Big Parade in Los Angeles and then boldly strides across America from Austin to Atlanta as communities everywhere embrace the walking revolution.

There are over 300 staircases in L.A. and a resilient group called City Walkers is determined to climb them all while tweeting. Equally surprising is a fast and furious journey on the Gold Line, a public transportation adventure with breathtaking views of L.A. that can't be seen through the windshield of a car.
