Chicago is a city in constant motion, filled with runners and bikers and power-walkers. NBCChicago's Stride blog is dedicated to keeping this city moving. We cover Chicago's running community, offer tips on trails, best practices on work out regimens, gear recommendations and more. But we're not the experts -- you are. So talk to us, tell us about your run, share what's on your iPod or that new stretching technique. We want to know!
