Late last December, Emily Ford, 28, of Duluth, Minnesota, took her first steps on Wisconsin’s 1,200-mile Ice Age Trail with a borrowed sled dog named Diggins. “I was laid off from my job as head gardener at the Glensheen Mansion, and I took full advantage,” she says. Ten weeks later, she became the first woman and second person ever to thru-hike the IAT in winter.
