I saw something on facebook for Annual Passholders and DVC members to check their email for a 2014 WDW Marathon Weekend offer...did anyone get it? I didn't, since I'm neither, but I'm wondering what kind of offer there is. You know, because I'm an addict, who would consider going if the deal was right. 
Just checked the DVC members website, no news (yet) wrt a 2014 WDW Marathon Weekend offer. 
Maybe tomorrow. 
The thing that I saw said to keep checking the respective member websites, and that the discounts would be in VERY limited release.
I just found this in my DVC members website:
"runDisney offers Member discounts PLUS early registration!"
"runDisney is a series of half marathon and marathon events that provide runners unique opportunities to run through Disney theme parks. Race participants earn Disney-themed medals, experience legendary Disney entertainment and Guest service and ultimately celebrate their accomplishments with a Disney vacation. Disney Vacation Club Members now get a $10 discount off first-tier registration prices for all runDisney half- and full-marathon races, plus limited early registration* in advance of the general public!" DVC Website
I just saw the same... our friend Sarah over at RunningAtDisney.com just put up a story with this information in it and links to where you need to register for the discount.
$10?!?! That's all? Meh. I'll just have to SUPER ENJOY the Wine and Dine Half and set my sights on Goofy 2015.
