This year for Marathon Weekend I did the 5K with my friend and then my first half marathon. Looking towards next year (yes, Disney easily moved me off my "one and done" pre-race stance), my friend would like to add the 10K. I have NO desire to do the full marathon, hence no Dopey for me. Then I got to thinking - in the past I had a schedule conflict which prevented me from doing the Princess weekend, but that conflict won't be an issue in 2020. Looking at the course maps, the Princess races appear to be basically the same courses as the marathon weekend. So other than the theme and the ability for me to complete the glass slipper challenge (a HUGE pro in my book), is there anything else that is substantively different between the two weekends?
