When I run to/ from work I've nearly been taken out a few times by cyclists flying out of blind bends!
That is as well as mp3 deaf peds, dogs, dog- walkers with trip wires etc?
One of these said cyclists cut up my inside as we both approached a corner, no warning bell or shout and he frightened the life out of me by shooting just past my elbow.
He works at my place and I had a serious chat with him the next day.
Funnily enough, I purposefully annoyed him this week by draughting him as per a post of mine.
