Lace up your shoes for the Cornerstone Lakes parkrun, a vibrant 5K community event taking place on September 12, 2026, in West Chicago, IL. This free, fun, and friendly weekly gathering welcomes participants of all abilities to walk, jog, run, or simply enjoy the atmosphere. The course features two clockwise laps on permanent paved paths that encircle the main lake, offering a generally flat and fast experience ideal for those chasing a personal best or simply enjoying a scenic outing. While the paths are well-maintained, be aware that some sections may accumulate mud, leaves, or puddles after rain.

Cornerstone Lakes parkrun prides itself on its warm and welcoming community spirit. It's an entirely volunteer-organized event, fostering a supportive environment for everyone, from first-timers to seasoned runners. After crossing the finish line, which is conveniently located adjacent to the main parking lot, runners often gather for a post-parkrun coffee at a local Starbucks, a cherished tradition that extends the camaraderie beyond the course. On race day, typical conditions for mid-September include comfortable highs around 78F and lows near 56F, with a minimal 12% chance of precipitation.
