in my younger days i was really into running ...70+ miles/week
i always ran with music...so i am sympathetic to the runners
it is the responsibility of the party overtaking a slower mover (be it bike around runner or car around bike) to take extra care to avoid injuring or startling the slower person
of course.....if you are the one getting hit...you tend to bleed more...so i am much more aware of my surroundings now
this for someone who almost got creamed by a cb&q freight train running, been hit by two trucks...without getting really hurt with either incident....until i fell off my bike a month ago...trying to be careful
