This is something I always wanted to animate. The exploding power of a pro sprinter girl. And this in slow motion :-)
Just, you can't find any motion captured cycles of such a track run. All you get is the typical all day running made for typical games. By accident I found a motion capture that was quite near, but not still what was in my imagination. And it didn't really fit to a muscle loaded girl, a lot of clipping. So I took frame for frame of this motion capture and modified it to a more athletic style and tried to reduce the major muscle clipping.
I will see if I can make more track and fields sports animations, ... for sure there will be a hurdle run, the exploding power when flying over the obstacles.
Have Fun! :-)
