Any running that covers a distance further than a marathon is called ultrarunning; the event is an ultramarathon. Such events can be measured in distance (for example, 100 kilometers) or by time (whoever has run the farthest after 24 hours).

The science and technology depicted in Silent Running are not always plausible, and Trumbull's special effects are low quality even by the standards of the time (he had a larger budget in his later film Blade Runner), but the melancholy message is powerful.
