The Signal Hill Speed Run

n 1975, the Guinness Book of World Records TV show called skateboard promoter James O'Mahoney and asked him to stage a skateboard race. The result - the world's first skateboard race, the Signal Hill Speed Run. It soon became an annual event, with crowds over 5,000 and national television crews, and competitors chasing a prize that didn't cover medical expenses of this most dangerous race.
