Hi, Danielle!
Great idea to start your plans - and your training! - good and earl.
Typically, registration for the following year's
Walt Disney World Marathon weekend begins in mid-March of the current year. You'll definitely want to check with
runDisney around the first of March 2012 for important announcements regarding Marathon Weekend 2013.
You can book room-only reservations by calling (407) W-DISNEY 499 days in advance of your arrival. Bear in mind that the rate you will book is the current rate; these rates are subject to change at any time, and that includes increases and discounts. You will not be able to book packages this far out, but you can certainly lock in your room reservations right now.
At 180 days before your arrival, you can make dining reservations by calling (407) WDW-DINE or by accessing Disney's
reservations site.
And do remember that runDisney has provided a variety of
training plans created by
Jeff Galloway, official training consultant.
Train safe, and happy feet!
See you later, celebrator!
