Race Info

The Bear Chase Trail Race

The Bear Chase Race Endurance Festival is a 100K, 50 Mile, 50K, Half Marathon and the Baby Bear 10K 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 race. The course is pretty fast (by trail/ultra standards), and not overly technical.

Voted Best Trail Race in Competitor Magazine’s “Best Of” runner poll, 2010-2016.

Parking

Runners will be shuttled to the Start/Finish area from an off-site parking lot (details coming soon).  Spectators with a daily or annual Bear Creek Lake Park pass may park inside the park at designated lots, (a short walk from the Start/Finish area), or take the free runner shuttle.  Volunteers will park in a lot adjacent to the Start/Finish area for free.

Cup-Free Racing

In an effort to minimize trash on the trails, The Bear Chase is a CUP-FREE RACE. We will not provide paper cups for water and electrolyte drink, and all runners will be responsible for carrying their own refillable hand-held bottle or hydration system. With an average distance of only 2.5 miles between each aid station, you’ll appreciate not needing to overload your bottles with fluids. Paper cups will be provided for soda, however you will be required to throw your cup away before leaving the aid station. Also, following the trail runner mantra of “leave no trace”, any runner found intentionally littering on the trail will be disqualified from the race.

Course Cutoff / Limit

There will be a hard cutoff for all ultrarunners at 6:00pm. Any runner who has not started their final lap by 6:00pm will not be allowed to continue. 100K runners missing the hard cutoff will be given credit for a 50M finish, but will be excluded from age group awards. After 6:00pm, we will have rolling cutoffs at each aid station following a 16:45/mile average pace. The course limit is 15 hours for the ultras and 4 hours for the half marathon.
