The Disney 100 Years of Wonder Marathon (sometimes referred to as the Disney 100 Movie Marathon) was a special commemorative event held to celebrate the centennial anniversary of the Walt Disney Company. Unlike a traditional "runDisney" race, this was primarily a cinematic event where select theaters showcased a back-to-back screening of "The Big Four" animated classics: Beauty and the Beast, Aladdin, The Lion King, and Frozen. For fans of the parks, the "100 Years of Wonder" celebration also included a year-long festivities at Disneyland Resort, featuring the debut of the "Wondrous Journeys" fireworks and the "World of Color – ONE" water show. While runDisney often hosts marathon weekends, the specific "100 Years" branding was more focused on a global celebration of storytelling across film and theme parks. If you are looking for an actual running race in 2026, you should look toward the Walt Disney World Marathon Weekend, which continues to be the flagship endurance event for the company, often featuring anniversary-themed medals even after the official "100" celebration concluded.
