I'm not saying the jogger wasn't an idiot, but if I had to allocate blame, it would go to the cyclist (or at least 90% to the cyclist).
Would get thrown out of court. Called "contributory negligence". Basically both parties at fault and it's a wash.
Personal opinion is that yeah, there's some cyclist responsibility but the jogger was a dope. I got one the same way about a year ago. Only one I really feel for was the one running with two dogs I spooked with an "on your left" and she face planted in the trail when she tripped looking back.
