Reddit reviews The Art of Sprinting: Techniques for Speed and Performance

This may help.

Or this.

I know even in military combatives classes they taught us "you're learning just enough to get yourself fucked up if you get froggy". There's no reason to get to blows with someone unless you're looking to do that anymore, so going halfway into training for it doesn't sound smart.

I suppose you could try to learn on your own by reading a book like The Mechanics of Sprinting and Hurdling (a very good book, by the way), but even so, you would at least have to be able to film yourself, which is harder than when lifting for the obvious reason that you are not stationary. You could get a training partner to operate the camera, but then you are no longer really learning to sprint on your own, are you?

Edit: This book is also quite good, and arguably more practical, though less thorough.
