Hi, Alison!
I am so sorry you will not be able to participate in the 2015 Disney Princess Half Marathon, but it's great news to hear you are already planning for 2016.
Typically this race event is held the last weekend of February, but dates will not be officially released until early 2015 and are always subject to change.
Lastly, if you should find yourself in the position to participate in any of the 2015 runDisney events, don't forget to register for
runDisney Email Notifications. This is a free service and will keep you up to date on registration information and race details.
I hope this helps, Alison! Please do not hesitate to contact me with any additional questions you may have regarding the Disney Princess Half Marathon, or any runDisney events.
Have a magical day!
Faith
