Lace up your shoes for the Cornerstone Lakes parkrun, a free, fun, and friendly 5K community event held every Saturday morning at Cornerstone Lakes Park in West Chicago, Illinois. Taking place on June 6, 2026, this weekly gathering offers a welcoming atmosphere for walkers, joggers, and runners of all abilities to enjoy the outdoors and get active. Typical race day conditions in early June boast pleasant highs around 79°F and comfortable lows near 57°F, with only an 18% chance of precipitation, creating ideal running weather.

The flat and fast course at Cornerstone Lakes is a highlight for many participants, featuring two clockwise laps entirely on paved paths around the perimeter of the main lake. While generally smooth, some sections of the course may occasionally have mud, leaves, or puddles after rain. The start and finish lines are conveniently located adjacent to the main parking lot, making access straightforward with free parking available off Smith Road. Cornerstone Lakes parkrun is entirely organized by dedicated volunteers, contributing to its reputation for "good vibes" and "warm, welcoming people."

What truly sets Cornerstone Lakes parkrun apart is its strong sense of community. Beyond the 5K, participants are invited to gather for a post-parkrun coffee at a nearby Starbucks, fostering connections and camaraderie. Having celebrated its first anniversary in April 2024, this established parkrun consistently delivers an engaging experience, drawing participants who appreciate its well-managed, inclusive environment. Whether you're aiming for a personal best on the fast course or simply looking to enjoy a scenic walk around the lake, Cornerstone Lakes parkrun offers a wonderful opportunity to be active and connect with fellow enthusiasts.
