What type of special event is "RunDisney" known for hosting?

RunDisney is renowned for hosting themed marathons and races, making this the correct choice. These events combine the excitement of running with the immersive atmosphere of Disney, featuring various race distances such as 5Ks, half-marathons, and full marathons, often held at Disney parks. Themed runs usually incorporate beloved Disney characters and stories, providing participants with unique experiences that go beyond typical road races.

In contrast, annual holiday celebrations, exclusive character meet-and-greets, and seasonal parades are all events that occur at Disney parks, but they do not specifically relate to the running and marathon themes associated with RunDisney. Thus, while other options might be engaging aspects of Disney offerings, they do not accurately capture the essence of what RunDisney represents.
