A creature that can run in a muddy terrain?
Pigs do it pretty well.
But if sinking is an issue, the creature needs to be smaller with large feet (like some birds) or really weird.

somehow warrior riding pigs doesnt seem like an image that would strike fear in the hearts of their enemies haha.
Sinking would be an issue if these marshes/bogs/whatever they are deep. In real life Earth, would they? Even if, by Charerg's suggestion, the terrain is of a tad higher altitude and drier?

PS: massive thanks for all the feedback, this is superb.
