The Dopey Challenge is a great way to see and experience Disney. It was my first year running it, but it was their second year offering the Dopey Challenge for marathon weekend. It's 48.6 miles in 4 days. The courses were in Epcot, Magic Kingdom, Animal Kingdom, and Hollywood Studios. The races are super early, with Florida weather being a bit cold because of how windy it was. But, the atmosphere and the runners are amazing and so upbeat! You really experience the "running high," and Disney happiness! The hotels are extremely accommodating for runners to get to and from the expo and starting lines. I highly recommend doing the Dopey Challenge if you want to run the marathon - it's expensive but so worth it. The shirts are all long sleeve except the 5K shirt, and there is a lot of swag to buy! We made a week vacation out of it, which was awesome to walk around the parks after the races. You are exhausted but so happy!
