You can not run on the road, in fact from what I hear security will pick you up if they find you there. When we stayed last year we went to the all-star or Con. Springs most days, it wasn't to big a hassle.
The other option is to run around the parking lot. There were 2 or 3 morning when I actually saw 2 or 3 other people doing the same. One warning, it's boring as anything and you'll have to do a few laps to get any type of distance. If I remember correctly it's about a 6 min loop or 3/4 a mile if you go along the entire outside of the lot
