Sam Gardner from Houghton, MI (far reaches of the Upper Peninsula) set off on January 1st to solo hike all four of the continental U.S.' long trails. Starting with the North Country Trail (which has only one recorded thru-hike in winter), Gardner will hike east to west, before moving to the Pacific Crest Trail, then the Continental Divide, and finally the AT. Back to back to back. To back. With the mileage totaling over 12,500, Gardner's lofty goal of finishing the trip in one year requires an average of over 34 miles a day. He does note on his site that his real goal is to finish, no matter what the time frame. You can follow Sam along on his trip at his site, which is regularly updated with his progress. We're pullin' for ya' buddy, Triple Crown +1.
