Lace up your shoes for the Cornerstone Lakes parkrun, a vibrant 5K community event held every Saturday morning at Cornerstone Lakes Park in West Chicago, IL. This free, fun, and friendly gathering welcomes walkers, joggers, and runners of all abilities to tackle its inviting course. Scheduled for July 11, 2026, participants can anticipate typical summer conditions with highs around 84°F and lows near 64°F, accompanied by a 15% chance of precipitation.

The course itself is celebrated for its flat and fast profile, consisting of two clockwise laps on permanent paved paths that wind around the scenic perimeter of the main lake. While generally smooth, some sections may hold mud, leaves, or puddles after rain, adding a touch of natural character. Runners frequently praise the "good vibes" and "warm, welcoming people" that characterize this volunteer-led event. The start and finish are conveniently located adjacent to the main parking lot off Smith Road, ensuring easy access.

As a parkrun, Cornerstone Lakes emphasizes community and enjoyment, encouraging everyone to participate at their own pace. After crossing the finish line, many participants extend the camaraderie by gathering for a post-run coffee at a local Starbucks. Whether you're chasing a personal best on a speedy route or simply looking to enjoy a refreshing 5K in a supportive atmosphere, Cornerstone Lakes parkrun offers a fantastic Saturday morning experience.
