+1 For knowing your route

+1 For knowing some basic self defense

The last one got a friend of mine mugged in broad daylight while jogging on a MUP in Portland, ME. Portland isn't exactly a hair-raising place, but anyone desperate or deranged enough to attack someone probably has realized that the chick out there with her ears tuned to her mp3 player and not her surroundings is a better target than the one who conspicuously and consistently checks out her surroundings!

I would also throw in using the empowerment that bike riding can give! I always feel like tough sh** out on my bike, and there's no way I'm going to let someone take that away from me!!!
