Organized start. They have a ribbon to split runners up by different starts, according to your expected finish time. Course is all along PCH is is very scenic and beautiful. The only drawback of having the course be on PCH is that there is NO SHADE! I usually drink water once or twice in a race, and the heat and lack of shade had me drinking at every chance I could. My only recommendation to the course directors would be to possibly have a water sprinkler to run through midway in the course. Overall good flat course, and good for spectators since it is a mostly out and back race. Great expo! Lots of clothing, shoes, food vendors. I bought great arm sleeves there for only $15.
