Lace up your shoes for the South Boulder Creek parkrun, a vibrant 5K community event held weekly in scenic Boulder, Colorado. Taking place on Saturday, October 31, 2026, this free, volunteer-led race welcomes runners, joggers, and walkers of all abilities to experience the beauty of the South Boulder Creek Trail. Typical race day conditions for this time of year offer crisp autumn air, with highs around 62F and lows near 34F, and only a 6% chance of precipitation, creating ideal running weather.

The course itself is a flat, engaging loop that winds through a mix of paved and unpaved trails, starting and finishing just before the creek bridge, a short walk east from the East Boulder Community Center parking lot. Runners will enjoy a single counter-clockwise lap along the paved South Boulder Creek Trail and unpaved Bobolink Trail, followed by an out-and-back section southward on the unpaved South Boulder Creek Trail, including a unique passage through a tunnel under South Boulder Road. While the course is generally flat, the high altitude of Boulder can add an extra challenge, even for seasoned runners.

South Boulder Creek parkrun, founded on February 24, 2018, is more than just a timed 5K; it's a testament to community and healthy living. Participants appreciate the friendly atmosphere and the opportunity to connect with fellow enthusiasts, often gathering for a post-run coffee. While formal aid stations are not part of the parkrun model, restrooms are conveniently located inside the East Boulder Community Center and portajohns near the parking lot. With its inclusive nature and picturesque setting, this event provides a perfect opportunity to achieve a personal best or simply enjoy a refreshing morning run.
