Inaugural Disney’s Princess Half Marathon Weekend to Create Fairy Tale Experience for Runners in 2009
Fantasy-filled weekend to feature popular Disney princesses; Event expected to rank among nation’s biggest women-specific endurance events
LAKE BUENA VISTA, Fla. (May 2, 2008) – Disney’s Wide World of Sports is creating Disney’s Princess Half Marathon Weekend, a new fantasy-filled event in 2009 designed to bring to life the “princess” in women runners of all ages and abilities.
The weekend event, scheduled for March 6-8, 2009, involves a health and wellness expo tailored for women, as well as two road races – a fun 5K and a signature 13.1-mile half marathon – through multiple Walt Disney World theme parks, all themed around Disney’s popular princess characters. In all, more than 10,000 runners are expected to participate, making it one of the country’s largest road races geared toward women and the only race runners can experience a storybook start and a fairy tale finish. Women and their family and friends will also have the opportunity to participate in a post race celebration at Magic Kingdom.
Disney’s Princess Half Marathon is the latest addition to Disney’s Endurance Series, which gives recreational athletes of all ages and abilities the chance to walk, jog, run, bike and swim their way “around the world.” From running marathons to road races and triathlons, participating athletes from around the world compete to stay in shape, to achieve personal-best times and often to raise donations for charitable causes.
“Disney’s Princess Half Marathon Weekend is a wonderful opportunity for women and girls of all ages. Disney princesses have attributes that all women want to possess: courage, loyalty, strength, commitment and perseverance. We feel this weekend is an opportunity to recognize those attributes within each woman and celebrate their accomplishments,” said Kathleen Duran, sports area manager for Disney’s Wide World of Sports.
Registration for Disney’s Princess Half Marathon Weekend opens on Monday, May 5, and is $120 for the half marathon and $40 for the 5K event. Participants can register online at
