The Phoenix Rock'n'Roll half marathon is a ton of fun and a great way to view the red rock scenery in Tempe. This race does not really go through Phoenix proper, in case anyone is looking for that experience. However, the scenery is beautiful, especially in January.
I felt there could have been a couple more aid stations on course and at the time, parking was a bit lacking, but that could be better now. Overall, it was a great race and a fun time!
