So I am looking to make a side view running animation of my character Ophira. What I am seeking in terms of speed is something like Sonic the Hedgehog, Saitama from One Punch Man or just general crazy super fast running. Not so much like classic Sonic spinning legs, but something where you can see the legs moving albeit motion blurred.

I'm likely going to just go with the whole "Naruto run" method of having her arms simply held straight back as I find the arms moving to and fro in crazy fast running to look a little silly.

So if anyone has any gifs or videos of what I am seeking that would be helpful to me so I know where to start with this.
