The Bear Chase

Join us this October for fall colors and fabulous trail running at the 2026 edition of The Bear Chase Trail Race!

Choose from a 100K, 50 Mile, 50K, Half Marathon, the ‘Baby Bear’ 10K or the newly added 5k trail race at beautiful Bear Creek Lake Park, in Lakewood, CO.
An excellent race for first time trail and ultramarathoners, runners will experience a variety of challenging terrain and sweeping panoramic views throughout!
The course is as runnable as it is beautiful, and is begging for Personal Bests.
Even better? A portion of proceeds from Bear Chase registrations goes straight to benefiting the trails and open spaces of Lakewood.
We hope you’ll join us for trail running at its best at the Bear Chase this October!
