The BIGDOGBRAG is a great, interesting obstacle course with really unusual obstacles that I haven't seen in other obstacle races. The setting is really nice with a view of Pikes Peak in the background and there are climbs out of canyons on ropes and cargo nets! After you run the 5k, they let you run the 2k with your younger kids who are registered for free....it's plenty challenging but an awesome experience to do with the whole family too!


Great Race!

This race was great. They mixed a good terrain with obstacles and it was an awesome local OCR. No emphasis on competition and the organizers were very friendly and motivating. Obstacles aren't the toughest out there, but the mix of obstacles and running was perfect. This is an OCR all about fun and the organizers and volunteers do an awesome job conveying that message.

A friend of mine, my daughter, and I, have done the Big Dog Brag every year since it first started in Colorado Springs. That should speak for itself as a review, we wouldn't do it, if it wasn't so awesome! There is lots of mud, lots of smiling, and lots of fun obstacles. We will definitely do it again in Colorado Springs next year! :)

Just did the BDB CS today and I must say I was really impressed. While, the obstacles aren't as challenging as other OCRs, it was still very enjoyable. The volunteers/staff were awesome. They helped to facilitate a very friendly and fun atmosphere that resonated throughout the waves of runners on and off the course. I especially loved how they utilized the venue and built many obstacles into the hill sides. I also really like the fact that this is a locally run race that directly benefits the community by promoting their many local sponsors.

I will definitely be back next year and I would recommend this to beginning and experienced OCR runners alike.
