This was the first half marathon I ever did. It set a very high bar that no race has ever lived up to.
The expo was top notch. It was a bit crowded, but very well organized.
Parking/Access: We stayed on Disney property and I would suggest this to anyone participating in the race (or races if you are in it to win it for the weekend). It is much easier to get around on Disney property, and even better, you get direct transportation to the race start the morning of the race. This is clutch because of the early start time for the race. Disney had it all down!
I LOVED the Disney course because you get to experience the parks. The starting line experience was thrilling with fireworks and lots of production value - really gets you hyped up. It is important to note that there is some highway running that isn't as scenic, but running through the parks made up for it! There were lots of character stops, but they ran very smoothly - and you don't have to stop if you don't want to. Each park was a cool experience, especially if you like Disney. There were only a couple of hills on over and under passes, but elevation was mostly flat. I really loved the course. For me, the best part was turning on to Main Street USA and seeing all of the lights. That was a pretty magical moment for me.
Finish Line: The finish line near Epcot was pretty cool.
Disney just has everything for an event like this perfected and they know how to do logistics and create an experience. I would recommend this for every runner as a race to add to your bucket list!
