The Records of Alone: Longest Stays, Fastest Exits, Biggest Weight Loss

Spoiler note: this post names winners and their final day counts.

I keep the placement and days-lasted numbers for every contestant across all 19 seasons and spin-offs in our season guides, and once you line them all up next to each other, a few records jump out fast. Here's the real leaderboard.

Longest stays

Roland Welker's 100 days on season 7 is the number people usually reach for first, and it's the longest by a wide margin. But it comes with an important asterisk: season 7 changed the entire format to a fixed 100-day survival goal rather than last-man-standing, so Welker wasn't outlasting the field in the traditional sense, he was hitting a target nobody else reached. He built a semi-permanent log shelter with a shortened crosscut saw and lived off a longbow, gill net, and snare wire through an Arctic winter, dropped off in September 2019 and extracted that December.

If you're looking for the longest stay under the standard last-man-standing format, that's Zachary Fowler's 87 days on season 3, followed closely by William Larkham Jr.'s 84 days on season 11 and Carleigh Fairchild's 86 days, also on season 3, in second place that same year.

Rank	Contestant	Season	Days	Note
1	Roland Welker	US 7	100	Fixed 100-day goal format, not last-standing
2	Zachary Fowler	US 3	87	Longest last-man-standing win
3	Carleigh Fairchild	US 3	86	Medically evacuated one day before the finale
4	William Larkham Jr.	US 11	84	Won via homemade gill net strategy
5	Timber Cleghorn	US 11	83	Voluntary withdrawal, runner-up

Fastest exits

The other end of the spectrum belongs to Desmond White on season 2, who tapped out after roughly six hours, the shortest documented stay in the show's history, after finding bear scat near his camp and feeling too vulnerable without a weapon to continue. Josh Chavez holds the equivalent record for season 1, tapping out after about twelve hours, also over fear of bears. Neither of these is a hunger story or a skills failure. Both are almost pure fear responses to the reality of true isolation hitting before the first night is even over.

That pattern, fast exits clustering around predator fear rather than physical hardship, holds up across the whole franchise. If you want the fuller picture of why week one is statistically the most dangerous stretch of any season, we've broken it down in our piece on early tap-outs.

Biggest weight loss

This is where the show's medical side becomes unavoidable. A few figures stand out:

• Alan Tenta, the season 10 winner, lost 78 pounds over 66 days, the largest raw weight-loss figure documented across the contestants we track.
• Zachary Fowler lost roughly 70 pounds over his 87-day season 3 win, about a third of his starting body weight.
• Carleigh Fairchild lost close to 30% of her body weight before her medical evacuation on day 86 of that same season, with her BMI falling to 16.8, just at the show's mandatory pull threshold of 17.
• Nathan Donnelly lost about 26% of his body weight over 72 days on season 6, before a shelter fire ended his run separately from any medical pull.

Worth noting: these percentages and totals come from a mix of contemporaneous reporting and the show's own medical framing, and different seasons haven't always disclosed the numbers the same way, so treat these as the best-documented figures rather than a perfectly uniform dataset.

What the records actually tell you

Put together, these numbers tell a pretty clear story about where this show is actually dangerous. It's not a slow, even grind. It's front-loaded with fear-driven exits in the first week, then it gets genuinely medical in the back half, where BMI thresholds and weight-loss percentages start deciding outcomes as much as willpower does. The winners who show up in the "longest stays" table aren't just tougher than everyone else, they're the ones who found a food strategy, whether that's Welker's gill net and longbow or Tenta's fishing and smoking setup, that let them slow the weight loss curve just enough to still be standing (or medically clearable) when the field around them wasn't.
