About Thunderdash...

What is ThunderDash?

The Original ThunderDash obstacle course race OCR is a 5K mud run with obstacles that include but are not limited to mud, climbing, mud, crawling, mud, 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. The obstacles are man-made, nature-made, and of course a combination of both. Many of the obstacles will encourage team efforts for easier completion so call your buddies and sign up today.

Not the muddy type?…..

5K Fitness Trail Run! – No Mud or Obstacles

The 5K Fitness Trail Run has you completing a 5K trail run with “Fitness Stations” located along the route spaced about 1/2 mile apart. No Mud or Obstacles but still the great challenge that THUNDERDASH is known for. Expect a 5K course on well-worn and groomed jeep trails through coastal and bermuda hay fields with stations where you will have to complete basic “Boot camp” style calisthenics. We’ll probably warm you up with some jumping jacks or maybe some squats but you can count on the evil BURPEE  (Check out How to do a Burpee) somewhere along the course. You won’t set a 5K PR but you will finish with a great sense of accomplishment and massive bragging rights.


10K Combo Fitness/Mud Run!

Complete the 5K Fitness Challenge and immediately continue your run onto the original THUNDERDASH course for a total 10K Ultimate Challenge!  Your timing chip will give you a split time between the trail run and the mud run.
