Amanda Popa walked 2,652 miles last summer, the entire length of the Pacific Crest Trail. “It took me 5 months and 5 days,” she remembers, “from April 21 to September 26, 2018.” Starting in Campo, a small town on the United States-Mexico border, the trail goes through California, Oregon, and Washington before reaching its northern terminus at the United States-Canada border in Manning Park, British Columbia.
