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.
