Most people who dream of hiking the Appalachian Trail never start. Doc K. has started three times — and never finished. Now 55, he's back for a fourth attempt, and his story is a useful reality check for anyone eyeing America's most famous long-distance footpath.

His track record reads like a catalogue of everything that can derail a thru-hike. In 2019 he set off in early March with zero hiking experience and a 43-pound pack stuffed with the cheapest gear he could find; a foot injury ended things at Harpers Ferry, West Virginia. In 2020 he made it to Fontana Dam in North Carolina before the pandemic shut the trail down. By 2022 he'd only reached Bland, Virginia, having simply lost momentum.

So why go again? Partly pride, mostly the pull of the trail itself. He traces it back to watching the documentary 5 Million Steps, which planted the idea years before he acted on it. A divorce in 2017 finally gave him the opening to plan seriously. And that rough first outing in 2019 taught him something he keeps coming back to: the trail's culture of kindness. Trail angels, shuttle drivers and strangers' small gestures restored his faith in people, and he wants back into that world — plus, this time, the feeling of actually standing at the finish.

The lessons are worth absorbing if you're considering your own attempt. His first few weeks were miserable because he was overweight, under-prepared and carrying far too much. Gear and training matter, and so does knowing the trail's quirks — the community shorthand for it all (trail families, zero days, PUDs — 'pointless ups and downs') that he'd never even heard of before his first start. Early March is a common starting date from the southern terminus, which means cold, rain and mud are essentially guaranteed for the first stretch.

That's what makes this story relevant beyond one hiker's blog. The AT runs roughly 2,190 miles across 14 states, and the overwhelming majority of people who start a thru-hike quit — usually in the first few hundred miles. Doc K.'s persistence, and his cheerful framing of cold, rain and mud as part of the deal, is a reminder that finishing is as much mental as physical. He's writing about it as he goes, so if you're toying with the idea of a long hike, following someone mid-attempt is a far better primer than a highlight reel.

Who is this for? Not just aspiring thru-hikers. Section hikers, weekend walkers curious about trail culture, and anyone over 50 wondering whether a big adventure is still on the table will all find something here. The answer to that last question, evidently, is yes — fourth attempt pending.
