Hello, Lauretta! Thanks for bringing another great question to the Disney Parks Moms Panel.
I've run dozens of races, and my favorites are always the
runDisney events! You and your daughter will have a blast no matter which race you choose. The dates for 2020 have already been released, but registration won't begin until April. In the meantime, you can
sign up for email reminders to let you know when it's time to register! The registration process has recently changed, and if it's the same for 2020 as it was for 2019, you should be able to register both you and your daughter at the same time.
You'll have at least four opportunities to participate in a
runDisney 5K in 2020, with at least one virtual series available, too. The dates that have been released as of right now include the Walt Disney World Marathon Weekend Jan. 8-12, 2020 (with registration opening April 16, 2019), the Disney Princess Half Marathon Weekend Feb. 20-23, 2020 (with registration opening June 4, 2019), and the Star Wars Rival Run Weekend April 16-19, 2020 (with registration opening July 16, 2019). Currently, your other option for 2020 will be the Star Wars Virtual Half Marathon (which you can run at your own pace in your own location any time between Jan. 30 and March 31, 2020) with registration opening July 16, 2019. Walt Disney World Resort Annual Passholders and Disney Vacation Club Members can register before the general public, so check your Passholder or DVC newsletter for more information about those dates.
If this is your first
runDisney experience, I would recommend the 5K during the Disney Princess Half Marathon Weekend! While I love all of the
runDisney races, the Princess weekend is definitely my favorite.
Enjoy the race!
Amy
