Race Information

The Original ThunderDash obstacle course race OCR is a 5K mud run with obstacles that include but are not limited to mud climbing, crawling, jumping, etc. Located on a beautiful piece of land outside of Comfort, Texas, with natural mud pits, 30-foot deep rock quarries to climb in and out of, and much, much more. Not the muddy type? Join the 5K Fitness Trail Run – no mud or obstacles. The OCR obstacles are man-made, nature-made, and of course, a combination of both. Many of the obstacles will encourage team effort for easier completion, so call your buddies and sign up today!
