Let it go

You decide to leave the matter be. You are all here for the win, and that's all there is to it. Why should you hold a grudge such as this?

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

And indeed, it all seems to work. But at the start of the final lap, from the corner of your eyes, you can see the pony who kicked you earlier slow down, looking into your eyes with fury. By now it is clear that she has no chance of winning the race. But instead of enduring the fall in silence, she jumps up from the ground, and her entire body gets slammed into you. And by the time you get up from the ground, cursing into your bite gag, you too lose the race, with the possibility of getting your orgasm alongside it.
