It's horrible that someone had to die to bring this to our attention. This is something that drives me nuts when I see it happening. I remember in the Strider's 10-miler being told by the police officer that we should run with traffic. I remember yelling back for her to learn the laws she was there to enforce. My dad was a cop in a Chicago suburb and always told me the LAW was to run against traffic. I tried looking for the UT State law and came across the following flyer.
http://www.ci.slc.ut.us/transportation/Pedestrian/pdf/PedestrianLawsBrochure11_05.pdfIt states that we should be on the sidewalk but if in the street we should go against traffic... I think that Andy Browning's point about running against traffic is the best. Also, I've noticed I am 100X more likely to have things yelled at me if I'm running with traffic than against traffic. Finally, I know of at least three different women in three different states that made the mistake of running with traffic with headphones on and had a car pull up behind them, the passenger reach out the window, and grab them as they drove off...
RUN AGAINST TRAFFIC SO YOU CAN SEE WHAT IS COMING! DO NOT TRUST DRIVERS!!!
