Whether a substrate is silt, sand or gravel may represent different challenges for running in similar sized animals. Particle sizes that include silt and sand result in a substrate that is even, but the particles move underfoot (Greenville and Dickman, 2009; Li et al., 2012).

The angle of repose, or critical angle of repose, of a granular material is the steepest angle of descent or dip relative to the horizontal plane to which a material can be piled without slumping. At this angle, the material on the slope face is on the verge of sliding. The angle of repose can range from 0° to 90°. The morphology of the material affects the angle of repose; smooth, rounded ...
