Hi Patricia!
The runDisney race dates for 2015 have not been set yet. RunDisney is constantly monitoring races and runner feedback as they make and adjust each year's schedule.
But, I can give you a guideline as to when the races generally occur, and what events they include, as of now. Events and race weekends are always subject to change:

January- usually the second weekend is Walt Disney World Marathon weekend. (full marathon, half marathon, 10K, 5K, and Kids Races)
February-- around the last weekend in Feb. is Princess Half Marathon weekend (half marathon, 10K, 5K, and Kids Races)
May-- around the first weekend in May is Expedition Everest Challenge weekend (5K/scavenger hunt, Family challenge edition and Kids Races)
