Cody Taylor returns to the Free Outside Podcast after completing one of the most ambitious unsupported hiking efforts on Vermont’s Long Trail: a complete out-and-back, also known as a Long Trail yo-yo. Cody began near the Canadian border carrying a 51-pound backpack loaded with 16 days of food. He traveled the entire length of the Long Trail to its southern terminus—and then turned around and hiked the whole thing again. With no resupply, Cody covered approximately 550 miles and 135,000 feet of elevation gain in 17 days, 8 hours, and 42 minutes. Having previously pursued an unsupported Fastest Known Time on the Long Trail myself, I know how deceptive this route can be. The mileage only tells a small part of the story. Vermont’s wet rocks, roots, mud, steep climbs, technical descents, and rugged northern mountains make it one of the most relentless long-distance hiking trails in the United States. Cody shares how he planned nearly 4,000 calories per day while keeping his food weight under two pounds a day, why he carried a stove and hot meals, and how running short on food affected his final 30 miles. We also break down his backpacking gear, shelter, sleep system, rain gear, electronics, footwear, and what he would change before attempting another multiweek unsupported adventure. The trip included days of heavy rain, flooded trails, dangerously cold conditions, terrible sleep, and as many as 20 falls per day during the opening section. Cody explains how he recognized the early signs of hypothermia, why he continued moving, and what happened when exhaustion caused him to hallucinate clowns beside the trail. Beyond the gear, nutrition, and Fastest Known Time, this conversation explores the mental side of thru-hiking, fastpacking, ultrarunning, and unsupported endurance challenges. Cody describes how he progressed from experiencing a panic attack during his first major project to feeling calm and grateful on the Long Trail. We discuss training for a 17-day effort, starting conservatively, adapting as the pack becomes lighter, and why it is impossible to prepare perfectly for an adventure of this scale. We also talk about Cody’s relationship with endurance athlete and mentor Ray Zahab, his transition from traditional ultramarathons toward expedition-style projects, and why the experience ultimately matters more than the record. This episode is for anyone interested in the Long Trail, Appalachian Trail, thru-hiking, backpacking, fastpacking, ultrarunning, FKTs, outdoor adventure, endurance training, hiking gear, trail nutrition, and the psychology behind pursuing enormous goals.
