See A Comparison of Marathon Training Plans for details. Some of the training plans might be adaptable for shorter ultras. While the advice does not directly translate, it can provide insight into general training principles.
Consider reading books on marathon training. Consider the Runner's World 50 mile plan, but think of the other online plans as input to creating your own plan rather than as a complete plan. Read the Umstead 100 guide it's free, it's short, and it has some outstanding advice for any ultra. "Training for Ultra Running" is also worth a read to get some insight into how the elites train, race, and cope with problems. Consider Wolfgang's "Ultra Marathon Training", but only in addition to the two books mentioned above. Read both "Relentless Forward Progress" and the "Field Guide to Ultrarunning" as these books have good information and reading both gives you some balance. For those wanting a high level summary, here's my recommendations: It's important to realize that there is little known about training for ultras, and while the books have the most detail, there's still a paucity of experience that backs them up. I have not used any of these plans, but I have selected them on the basis of having a reasonable level of detail and some credibility. Below are some selected ultramarathon training plans for various ultramarathon distances.
