Lace up your shoes for the Cornerstone Lakes parkrun, a welcoming 5K event set to take place on April 25, 2026, in scenic West Chicago, IL. This free, weekly community gathering invites walkers, joggers, and runners of all abilities to enjoy a refreshing start to their Saturday morning. The course itself features two clockwise laps on entirely paved paths, winding around the perimeter of the main lake within the beautiful 41-acre Cornerstone Lakes Park. Described by participants as a "flat fast course," it offers a great opportunity for personal bests or simply a pleasant outing, though runners should be aware that some sections may accumulate mud, leaves, and puddles after rain.

Cornerstone Lakes parkrun is renowned for its warm and friendly atmosphere, attracting a community of enthusiastic individuals who appreciate the chance to be active outdoors. While smaller in scale compared to some larger races, with typical attendance between 20-35 people, it has seen as many as 165 finishers, all supported by dedicated volunteers. The start and finish lines are conveniently located adjacent to the main parking lot off Smith Road, and while parking is free, car-sharing is encouraged. You can expect typical race day conditions in late April to be pleasant, with highs around 63°F and lows around 41°F, and a 19% chance of precipitation.

Beyond the run, the community spirit continues with a traditional post-parkrun coffee gathering at a local Starbucks, offering a perfect chance to connect with fellow participants. Although no formal aid stations are provided by parkrun organizers, a portable toilet is available during warmer months. Whether you're a seasoned runner, looking to get active, or simply want to enjoy a morning stroll in a friendly environment, Cornerstone Lakes parkrun offers a consistent and inviting experience.
