Have you looked at the BVH files from Santa Monica Studios? Almost 30Mb of free motion files that work pretty well with Poser. To get them to run in place: after importing the BVH's for a figure, open the Animation Palette and delete the figure's Hip's X & Z translation keyframes. Just takes a second. The zip file (free and hosted at Stanford Univ.) is huge and has a couple of hundred animations for bi-peds. ;-) http://movement.stanford.edu/santa.zip.
