Oh you were specifically talking about this one? Yeah I agree, wouldn't try to fight it but from what I have in my head (and based on how fast tiny crabs and spiders can be) I would still not run but always hide. Don't think you're gonna outrun it and you might make noise alerting it to your presence. I would only run if you're absolutely sure that you can outrun it and that the creature won't be outraged enough (which is a risk with certain supernatural creatures, bitches get easily offended) to keep following you without a line of sight
