I really like podrunner podcasts for indoor training,either elliptical or on the trainer. They have a series called couch to 5 k , 8 k, 10 k that start slow and short and increase in time and speed over a number of the podcasts. These start out with a warm up and then set intervals at a certain speed which increase in length from week to week, interspersed with short rest periods. They also have some nice fast stair steps series of increasing tempos. Their regular podcasts are usually a set time at a set pace which I find great for endurance training but these also have a warm up and cool down.
There is another podcast by the same guy called grove electric which also has some nice mixes. The best part of course is that they are free.
