This was a great race overall. You get to run through California Adventure, as well as Disneyland for the beginning portion before running through the streets of Anaheim. Towards the end of the race, you run past the Honda Center, and then through Angels Stadium. Yes, you run through Angels stadium (Mile 10ish). The last stretch of the run puts you through California Adventure one last time and then through Downtown Disney to the finish line. The course support was great, there are local high school marching bands and cheerleading groups throughout the course. You definitely feel the support and cheering as you pass by them. The post race was also great, you receive a decent amount of goodies once you cross the finish line, and you are cheered through by Mickey Mouse himself.
The only thing that could be an issue is the weather. I have run this half marathon 3 times, and one time the weather was brutal! It was 99 degrees by the time I had crossed the finish line, and it was 8:30 am! It is something that you do not have control over, but definitely keep it mind.
