We just booked our next vacation -- and although we're bona fide adults, we're super-stoked to be heading to Disney World for their annual Marathon Weekend in January 2013. But in order to get motivated, we figured browsing the attractions we'd see while running couldn't hurt. And what's more exciting than Cinderella's Castle at the Magic Kingdom? Um, nothing! [Ed. note: In fact, I'll be running through the castle come January 13.] Oh, and in case you're wondering, we booked the Waldorf Astoria Orlando for our stay.
