My observation during these two events was that those who were able to organise their anatomy, and maintain a their cadence whilst running through thick mud had the greatest success.
If you ask Dr. Google what your cadence should be, you'll probably get some form of advice telling you to run a cadence of 170-190 strides per minute. Rather than focusing on a particular number, I would suggest that your cadence should be as high as is maximally sustainable. I write this with some caution, as very often I find this piece of information to be dangerous in the wrong hands, or perhaps feet. There is more to running technique than just having a maximally sustainable cadence.
Maybe appropriately, running with a low cadence is like getting stuck in the mud. My goal with athletes I coach is to teach them to fly. Spending more time in the air, and less time on the ground.
