Will be staying in Khao Kho for about a week. Are there any dirt/gravel trails around that are suitable for running?

Not a usual pastime up here. The roads are there but depends on what part of Khao Kho and how hilly you want it.

Staying near the 2196/2325 junction. Hills are okay.

 

I used to run the roads and trails at Tat Mok fairly regularly.
