Patricia, animal run cycles are not simply walk cycles done quicker. When animals run, their legs move differently than when they walk. And all animals do not all run the same way, even the same animal (eg: horses) can have several different running styles.

On a slightly unrelated note: why are you tweaking a python script to speed up the walk cycle whenBlender already has tools that can do that?

sir howto do that? please guide. What I have done that its basically a 4 Leg Walk and with the different settings in the Bone Rotation and Bone Locations I have converted from 4 Leg walk to 4 Leg Run.
