Rattler Promotions kicks off the 3rd year of the summer mountain bike series at Bear Creek Lake Park in Morrison, Colorado. The series continues to grow and is a great family event for a weekday night in the summer time.  You will be treated to an amazing race scene, professional timing, a ton of prizes from our great sponsors, a volunteer group that is second to none, and super fun terrain.

Rattler Series is proud to be part of the Colorado Mid-Week Championships Series, joining RaceCo and HRCA.  This will be a 12 week race points system. 

Please note that since this is a park we all enjoy, we will be sensitive to weather conditions and this race CAN BE CANCELLED last minute.  Please see the Info page on race cancellation policies.

Race dates this year will be May 23, June 13, June 27, and July 11.  Like last year, we plan to start the kids race (10 and under) at 5:00 with other waves going off at 5:45 (ish) and 6:15 (ish).

Upon entering the park, please tell park staff you are there for the race.  Since there is no park entry fee at the gate, we will be asking for a $5 parking “donation” to help with keeping this a low cost event.

We look forward to another great year of racing and expect more racers this year than ever!
