Looking for a new and different place to run? I recommend one of the many running events at Disney.
Keep in mind that these events fill up fast. I suggest checking out this webite:http://www.rundisney.com/ and make sure to get on the mail list to know as soon as the registration opens up.
It is also best to stay on-site for one of these runs as it gives you and your party a ride to the race or to locations to watch the races.
You also are given a nice discount on resort and park prices. It is a great time to maybe try a moderate or deluxe resort for a couple days.
Remember to get those dining reservations in early (180 days) as well because the runners will be doing their carb loading.
I have personally run the Princess Half Marathon twice and what a great experience!! You get characters, music and so many more kinds of entertainment along the way.
