Adventure meal company Greenbelly debuted a short film today titled, Made of Grit, which features more than 30 thru-hikers nearing the end of the iconic Appalachian Trail. The hikers were interviewed on their second-to-last day on the trail, just before summiting Mount Katahdin, Maine.

“The film captures some powerful stories against a beautiful fall-foliage trail setting,” the filmmakers said.

Directed by Josh Hardwick and Britton Hardcastle, Made of Grit was a passion project for those involved. The founder of Greenbelly Meals, Chris Cage, has said that his hiking the nearly 2,200-mile-long trail was one of the inspirations for starting his company.

“We ended up hearing stories from over 30 of them just before they summited Mount Katahdin, marking the end of their adventures,” the filmmakers wrote. It does well to capture the emotions these hikers felt.

Greenbelly said that it hopes its 15-minute film helps to convey the strength (and, of course, the grit) of these dedicated hikers and that it gets others inspired to pursue something they’re passionate about.

The Appalachian Trail itself stretches from Springer Mountain, Georgia, to Mount Katahdin, Maine. This amazing stretch of East Coast wilderness is marked by roughly 165,000 white blazes and includes a variety of lowland and steep terrain, mostly made up of dirt, grassy or rocky paths. It’s been the focus of countless books, movies and other media, and has a deep history dating to its conception soon after World War I and its “completion” in 1937 — a term we use loosely because the route and maintenance of the AT is always at least a little bit in flux.

Because of that, there’s no definitive measure to how long trail is, because this year could be different than five or 10 years ago. Greenbelly’s founder said it was 2,185 miles long the time that he hiked it. It took him six months to complete.
