Lace up your running shoes for the Narrowleaf Lake Run, a cherished autumn tradition set for October 31, 2026, in scenic Loveland, Colorado. This family-friendly event, celebrating its seventh annual running, offers a perfect blend of challenging distances and picturesque views at Boyd Lake State Park. Choose your adventure with distances including a 10-mile, 7-mile, 4-mile, or a fun 1-mile pumpkin race, along with options for kids' fun runs. Typical race day conditions in late October boast brisk autumn air, with highs around 60°F and lows around 27°F, and a minimal 5% chance of precipitation, creating ideal running weather.

The Narrowleaf Lake Run is renowned for its exceptionally flat course, featuring almost no elevation gain, making it a prime opportunity to achieve a new personal record. Runners will traverse perfectly paved walkways for most of the route, with a short, enjoyable half-mile off-road section on the south loop, all while soaking in beautiful lake and wildlife views without any vehicle traffic. The course offers consistent lake views throughout. Aid stations are strategically placed, with the 4-mile route passing one station three times, the 7-mile passing two stations multiple times, and the 10-mile route accessing three stations multiple times to keep you fueled and hydrated. These aid stations are known for providing 100% plant-based snacks and drinks in biodegradable cups, and even offer water bowls for furry running companions.

What truly sets the Narrowleaf Lake Run apart is its unique connection to the landscape—named after the abundant Narrowleaf Cottonwood Trees that define Boyd Lake State Park. After crossing the finish line, celebrate your accomplishment with lively post-race festivities. Parking is conveniently located within a 1-2 minute walk of the start and finish lines at Boyd Lake State Park, ensuring a smooth and enjoyable race day experience from start to finish.
