When I used to do Muay Thai (kickboxing), I was given some very useful advice (which was directed at all participants, not just me).
Your number one skill is awareness so that you see potential threats before they become one and take decisive evasive action before anything happens. (Which includes trusting your spidey sense with roads with overgrown hedges, underpasses and walkways where you can't see what's beyond the lit area (Milton Keynes, I'm fucking looking at you there), the bloke you think might have been looking at you a bit too much or who is noticeably keeping in your blind spot and avoiding his reflection being seen in shop windows or offices by walking directly behind as you go home).
Then it is fitness, because you need the strength, stamina, balance and speed to run away. That was the majority of the sessions - intense aerobic activity, core strength, balancing, functional stretching, then actual glove/bag/pair work, then some sparring, then some final stretches to warm down. They were absolutely brutal training sessions twice a week, but incredibly effective physically; I felt balanced, poised and I was fast and strong.
Actual technical ability came way below those two.
None of that speed or fitness mattered when my then partner decided to batter the fuck out of me in front of the children. Because that's where the biggest risk lies to women - in the home. At best, the speed/reactions meant I was more able to bat away the things that were being thrown at me at first. Once he'd actually got hold of me by the throat, there was nothing any of the training could do because he was bigger and vastly stronger than me. And my feet were dangling in the air, so kicking anything was out of the question as well.
The only realistic chance a woman has is if she knows there is a problem sooner than waiting for him to make it clear there's a risk, is faster than the attacker (and that's not guaranteed) - and can sprint away at top speed for further than he can run.
