Sweating is evolution’s most efficient cooling strategy, allowing humans to stay on the move far longer than most fur-covered animals. But how much sweat is too much? Where should we be perspiring the most? (Our armpits? The backs of our knees?) And why does some sweat smell so much? These are among the questions that journalist, amateur athlete, and heavy sweater Tom Vanderbilt has pondered for years. In this episode, he finally gets them answered by Canadian chemist Sarah Everts, author of the new book, The Joy of Sweat: The Strange Science of Perspiration.

Every so often, Outside magazine publishes a collection of stories that fit into what we call a “zero to hero” package. The idea is to send our contributors out into the world to try something new that pushes them far outside their comfort zone. They might be asked to learn a new skill, break a bad habit, or even confront a long-held fear. For our most recent version of the package, our hope was to inspire our readers to set some ambitious goals for themselves after the long months of COVID-19 shutdowns. In this episode, six of our brave correspondents talk about their efforts to take on big challenges and why it’s pretty much always worth going for it even if you don’t succeed.

When we watch an elite endurance competition like the Tour de France, it’s easy to get caught up in the drama of moments that generate headlines—particularly the gnarly crashes that send riders slamming into the pavement. But while a crash is undeniably painful, the most agonizing part of professional biking is almost always the pedaling. If don’t believe that, talk to any racer who has dared to pursue the hour record—the longest distance cycled in an hour. In this favorite from our archives, we bring you the story of Italian cyclist Vittoria Bussi's excruciating quest to make history, and how the ordeal forced her to transform her relationship with pain.

All too often, life gets in the way of the things we really care about. So it was for Thomas Rhett, one of the biggest names in country music, whose rise to superstardom meant that he no longer had time for the outdoor experiences that had been such a formative part of his childhood. But then the pandemic struck, and suddenly he had time to play in the mud with his kids and return to adventuring. The result was a creative catalyst that gave birth to his latest album, Country Again: Side A, which captures the feeling of finding your way back to yourself after being lost in a world of obligations and distractions. Now, as Thomas Rhett prepares to take up the summer tour he had to cancel in 2020, he talks about how getting into the woods or on a river inspires him to tell the kinds of honest stories through song that really mean something.

In May, professional climber Jordan Cannon celebrated his birthday by publicly announcing that he was gay. Getting to this point wasn’t easy for Jordan—he’d had a hard time coming out even to close friends. But something inside him began to change after he met legendary Yosemite climber Mark Hudon, who became his mentor as well as a father figure. The two men, who are separated by 38 years, soon agreed to work together on an ambitious climb of Yosemite’s El Capitan. But what began as an unlikely athletic partnership turned into a life-changing friendship for both of them, that rare kind that allows you to fulfill your dreams in ways you never thought possible.

When our fathers tell us tales of their wild youth, we usually listen closely. This is partly because hearing about pop’s bolder, bearded past is entertaining. But more importantly, when your dad shares an experience from his younger days, you learn something about who he is—which gives you a glimpse into your own origins. This week, in the run-up to Father’s Day, we bring you the story of a family that wanted to better understand the meaning behind dad’s crazy stories. What they discovered is that his pursuit of adventure was all about transforming himself into the best kind of man and parent he could be.

When he was in his early twenties, Mason Earle was living the dream. After dropping out of college so he could climb full-time, he signed a sponsorship deal with a major outdoor brand and began taking climbing trips all around the world. But then, as he approached his 30th birthday, he was on a trip to Yosemite when he began experiencing flu-like symptoms that wouldn't go away. He would later be diagnosed with myalgic encephalomyelitis, commonly called chronic fatigue syndrome. In this powerful episode from our friends at the Death, Sex & Money podcast, Mason speaks with host Anna Sale about going from being an elite athlete to spending most of his waking hours in bed, the pleasure he now finds in the littlest things, and why he actually doesn’t miss climbing.

Just how long can someone last in the desert without a drink of water? That’s something listeners asked us after last week’s episode about Claire Nelson (“Alone and Injured in the Wild”), a solo hiker who took a fall in Joshua Tree National Park and ended up spending days waiting on the ground for a rescue. In this episode, we provide the answer in the form of a remarkable story from our archives. In 1905, a gold prospector named Pablo Valencia reportedly wandered through 110-degree heat in Arizona’s Sonoran Desert for six days before stumbling into a geology camp. He was about as close to dead as you can get while still breathing. His tale forever changed our understanding of the limits of human endurance.
