The first video below is the trot of a gaited horse (Icelandic Horse / Pony), with slow-motion included. Included
in the clips are a few strides of her downward transition at the end of the trot sequences.
The second and third videos below are the stepping pace of a gaited horse (first is Peruvian Paso, second is Icelandic Horse),
with slow-motion included.
Stepping pace is on the opposite side of the gait spectrum from trot. Trot will use the diagonals together
and stepping pace uses the laterals working more closely together (not quite as close together as the pace).
