Hi Siobhan!
Welcome to the Disney Parks Moms Panel. I'm glad to see that you are considering running a runDisney race! They are truly amazing experiences that not only bring you to Walt Disney World Resort, but also help to encourage a healthy lifestyle through training!
RunDisney race registration prices can fluctuate between the weekends and it's not uncommon for prices to not be released until registration opens. To give you an idea of the most current registration costs, I'd recommend checking out the
Registration tab for
Star Wars Half Marathon - The Dark Side. You'll see for this race the Star Wars Dark Side 5K is $80, the 10K was $120 (currently sold out), the Half Marathon is $185 and the Star Wars First Order Challenge is $330. For the runDisney Kids Race the Dashes are $20 and the Mile is $30. This will give you an idea of the range of registration prices, but as I said they can change slightly between each weekend. In addition to this, there is also an Active.com registration fee. To give you a ball park, when I registered myself and my son for Walt Disney World Marathon Weekend, the registration fee was roughly 7%.
Please let us know if you have any other questions.
