One April morning I left the Mexico border and walked north on the Pacific Crest Trail. For five months I hiked through the California desert, the snows of the Sierra Nevada, and the Cascade Mountains of Oregon and Washington. My goal was to succeed in an epic challenge: to hike 2,650 miles and reach Canada before the October snows. It was an unforgettable summer of sunrises, river crossings, and high mountain passes; of physical and mental challenges and peaceful wilderness camps under the stars. In the fall colors of September I reached the border of Canada.This is the story of my thru-hike.
