The Bear Chase Race Endurance Festival is a trail running event held at Bear Creek Lake Park in Lakewood, Colorado. It offers multiple distances including 100K, 50 Mile, 50K, Half Marathon, 10K (Baby Bear), and 5K, catering especially to first-time ultramarathoners and trail runners. The course features mostly dirt and single-track trails with a variety of challenging terrain and panoramic views, yet remains relatively fast and not overly technical by trail standards.

Elevation gains vary by distance, with the 100K having about 4,250 feet of gain. The event supports local open space preservation and provides a scenic, well-supported race experience. Visit the organization's website for the most recent information.
