Here is this week's speculative fiction writing prompt. I'm labeling it as horror this week, but take it whatever direction you choose.
You enter a zombie-infested 5K where the zombies are real, not made-up volunteers.
As always, feel free to use this in any way you choose. There's no need to give me any credit for any story you come up with. Of course, I never mind if you do give me credit for the writing prompt, but it's not necessary.
