As a beginner, I'm not sure what is reasonable or paranoid. I tend towards paranoid so I would love to hear some rational thoughts on this. I'm wondering if I should: 1) carry mace or pepper spray for dogs and, yeah, any two-legged predators as well 2) wear reflective clothing (smart or dorky?) 3) constantly change my routes to avoid stalkers? These are things I hear about but do most women runners really take these precautions?
