And…they’re off. Nearly 800 runners showed up in downtown Van Alstyne on Saturday to take part in the sixth annual Little Big Town 5K and one-mile fun run. The event was dedicated to Riley Sprowl — the Van Alstyne youth paralyzed in a December sledding accident — with proceeds going to benefit Riley and his family. See the Sports section for Jack Walker’s full report on the 5K and a list of the top finishers.
