Erin Azar, known to her nearly one million TikTok followers as @mrs.space.cadet, has become an unlikely hero in the world of running. Her rise to fame doesn’t come from setting records or showcasing an elite athletic physique. Instead, she captures the hearts of everyday runners by embracing the imperfections of the sport—and herself—through humor and relatability.
Erin’s journey began in the most unassuming way. A 39-year-old mother of three from a small Pennsylvania town, she started running as a way to cope with the challenges of motherhood and working from home. She quickly realized that traditional fitness content didn’t speak to her experience. "I wanted to see someone say, ‘Hi, running is hard. Come with me while I go for a run,’" Erin recalls. Unable to find content that resonated with her, she decided to create her own.
Her TikTok channel became a space where she could chronicle her struggles with running in an honest, self-deprecating way. Unlike the polished fitness influencers with perfect form and flawless gear, Erin shows up in mismatched outfits, admits to hating hills, and frequently questions whether the dampness in her clothes is sweat or something else entirely. This raw, unfiltered approach struck a chord with many who felt alienated by the typical running content that glorified speed and perfection.
Erin’s content is as entertaining as it is inspiring. In one series, she attempts various events of a heptathlon, despite not being a professional athlete. Her candidness about feeling out of her league is part of her charm. Whether she’s jumping hurdles with an Olympic silver medalist or crouching at the starting line next to sprinting star Aleia Hobbs, Erin’s antics are both hilarious and relatable. She’s not there to win; she’s there to remind us that running—and life—doesn’t have to be perfect to be meaningful.
Beyond the humor, Erin’s videos convey an important message: running isn’t always pretty, and it doesn’t have to be done perfectly to count. “There’s a whole subset of people who are just getting through a rough day with a run,” Erin says. She has become a beacon for those runners, reassuring them that it’s okay to struggle, to walk-run, and to question why they’re even doing it in the first place.
Despite her self-proclaimed “back-of-the-pack” status, Erin has achieved what many seasoned runners dream of—partnerships with major brands like Nike and Athleta, and even a role as the Official Hype Woman for USA Track & Field. It’s surreal, she admits, that someone who doesn’t track her pace and has no idea what her personal best on a mile is could land deals with world-renowned sports megabrands.
Erin’s success lies in her authenticity. She’s not trying to be the fastest or the fittest; she’s simply being herself. And in a world where social media often feels like a highlight reel of unattainable perfection, Erin’s willingness to show the messy, sweaty reality of running is a breath of fresh air.
When I meet Erin for a run on a winding, hilly road in her rural hometown, she’s exactly as she appears in her videos—warm, welcoming, and refreshingly honest. There’s no script, no shot list, no retakes. Just Erin, offering me the use of her bathroom before we head out, wearing what she calls her “going to the airport” clothes because it’s laundry day.
As we run, I’m struck by how familiar the terrain feels to me, a fellow struggle runner. The historic barns, stone farmhouses, and grazing ponies are both incredibly scenic and incredibly daunting. But Erin isn’t fazed. She’s quick to explain that she doesn’t care about pace or performance. What defines her as a runner is having a purpose for why she runs.
For Erin, that purpose is clear: to inspire others to lace up their shoes and get out there, regardless of their speed, fitness level, or experience. And in doing so, she’s leading a movement that challenges the notion that the only reason to run is to run faster and better. Erin Azar may be a back-of-the-packer, but in the eyes of her followers, she’s miles ahead of the curve.
