A marathon, of course, is 26.2 miles long. Elite runners can complete these races in just over three hours. Ultra-running events can be one hundred miles long. And as grueling as that sounds, these events are growing in popularity.

It’s one of the featured films at this year's Somewhat North of Boston Film Festival in Concord. One of the directors, Mike Mooney, joined All Things Considered to talk about the film, noting that if someone traveled a hundred miles east from the NHPR studios, that person would be well past Portland, Maine.
