I... Think so? It looks like one but I couldn't follow her feet very well. "An easy way to tell the difference between a RW and a rack is running walk has a larger overstride behind and a deeper head nod with a fairly lever top line. It has four evenly spaced beats. It has a glidey back and forth motion. A rack has the same footfalls with a more ventroflexed back, a higher head set, less head nod and less overstride." I found that on another site when I was trying to figure out what my gelding was doing with his feet. It looks very similar to him with the short quick strides and high head. A rack can be super fun to ride in my opinion :) Hope that helps!
