For sprinters, there's the challenge of a marathon, a half-marathon and, of course, a 5, 8 or 10K run. Then there's the truly unique Windy City event that's the Chicago Quarter Marathon. Back for its third year in 2016, this one-of-a-kind 6.55-mile event has grown since its debut to be winner among local running enthusiasts. Held in early spring, it's also one of the very first warm- weather runs of the year.
