Kick her back

You chase down the woman, and kick her on the thigh strong enough that she collapses on the ground. Nobody is messing with you!

Learning from the experience the kick gave you, you decide to stay away from the flock, continously building up momentum as the rest of the ponies kick each other in a relentless fashion. The tactic seems to work, and you soon find yourself as the first. Your lead growing ever more thanks to Rita's rigorous training.

And indeed, it all works out. You pass the pony you kicked, crying on the ground from the pain, numerous times with each lap finished. You don't feel much remorse to be honest. At the end of the final lap, you get through the finish line as the first one, hearing the crowd cheer in excitement. Rita runs up to you with a wide smile, and starts leading you away. And you find yourself smiling also, as you know very well what is going to happen next.
