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.
