A New Zealander and an Irishman, quit their jobs, cash in their savings and walk 2,626 miles from Mexico to Canada along one of the longest and most challenging foot trails in the world, the Pacific Crest Trail. Their route takes them through some of the most spectacular scenery in North America, including California's deserts, the alpine lakes and granite peaks of the Sierra Nevadas, and the massive volcanoes and temperate rainforests fo the Cascade Mountains. Walking a challenging pace of 21 miles a day for 4.5 months, they must cross the Canadian border before winter storms hit the Cascades. The ordeal forced one of them to quit just 60 miles before the finish. This epic adventure is an exhilarating antidote to the predictability of modern life.
