Several additional celebrities are joining in the fun of the 20th anniversary Walt Disney World Marathon Weekend presented by Cigna. Comedian and The Price Is Right host Drew Carey, actor Gilles Marini (Sex in the City: The Movie, Switched at Birth and Dancing with the Stars), Access Hollywood co-host Kit Hoover, reality TV stars Ethan Zohn and Jenna Morasca (Survivor, The Amazing Race and Everyday Health) and actor Sean Astin (The Goonies, The Lord of the Rings and Rudy) are participating in the historic runDisney race weekend, Jan. 10-13. Zohn , Morasca, Marini and Hoover are running the 13.1-mile half marathon at Disney, while Carey and Astin are taking on the 26.2-mile marathon. They join celebrities Alison Sweeney (The Biggest Loser) and Colin Cowherd (ESPN radio personality) who already signed up for the half marathon. For many of these celebrities, competing in a runDisney event will be a familiar experience. This will be the second runDisney race for Carey, who ran in the 2011 Disneyland Half Marathon. Likewise, Zohn and Morasca both ran in the Walt Disney World Half Marathon earlier this year and the Princess Half Marathon last year. And Astin ran in the inaugural Tinker Bell Half Marathon at Disneyland Resort earlier this year. This will be the first runDisney event for Hoover, an avid runner, and Cowherd and Marini, who are both first-time half marathon runners. In all, nearly 50,000 runners are expected to compete in various events throughout the weekend with the 26.2-mile marathon field comprised of roughly 55 percent women – the first time ever that women have outnumbered men in the Disney Marathon field. The celebrity participants are just some of the new features of the Disney Marathon. Among the other new features are: A specially-designed 20th anniversary Mickey Mouse commemorative finisher’s medal with two spinning elements and engraved with two famous quotes from Walt Disney himself Enhanced entertainment at Mile 20 to celebrate the 20th anniversary New course routes through the Walt Disney World Speedway and the ESPN Wide World of Sports Complex A new post-race party at Downtown Disney The Disney Marathon Weekend presented by Cigna will again feature Kids’ Races throughout the weekend, including the Mickey Mile, as well as a Family Fun Run 5K on Friday, the Half Marathon on Saturday and the Marathon on Sunday.
