Disneyland Half Marathon Weekend

Hi all! I will be running in the Disneyland Half Marathon Weekend 10k Labor Day Weekend and I wanted to reach out to all of you to hear about your RunDisney experiences! I've never run one before and was wondering what the intensity is like? My mom and I are determined to run it all but I see so many cute pictures of people posing on the course, are there photo ops along the way? What's the overall experience like?
