Hey thanks for the other comments... most of them. I did try the running on the right thing and it seemed to work but also, it was 6 am so that might have helped. In either case I think I'll stick with that combination as it was the best bridge run I've had since the winter.
I don't know how to tell the runners to stay in their path in central park, I googled cycling forums and found you guys but I don't frequent any running forums so I don't know any good ones. I would advice against making any on the spot corrections because runners get upset when cyclists yell at them...
