EUGENE, Ore.—The American Association of Sports Psychologists issued a formal advisory Friday warning fitness enthusiasts against the dangers of "raw roading," a viral athletic trend in which participants run outdoors without smartphones, smartwatches, or headphones.

Originating on social media under hashtags like #NakedMile and #UnmonitoredStride, the challenge requires runners to complete a physical route using only their eyes for navigation and their own internal thoughts for entertainment. Sports scientists warn that the sudden absence of biometric feedback and digital stimulation can lead to acute spatial disorientation, pacing anxiety, and unexpected self-reflection.

"The modern athletic brain is not currently conditioned to process the mechanical thump of one’s own sneakers for thirty consecutive minutes without a true-crime podcast or a high-tempo playlist to buffer the experience," said Dr. Aris Thorne, director of the Human Performance Lab at Oregon Health & Science University. "We are seeing elevated levels of existential dread in athletes who, upon reaching their second mile, suddenly realize they are entirely alone with their own consciousness."

Marcus Vance, a 28-year-old amateur marathoner from Bend, Oregon, recently attempted a "silent half-mile" in his local park. He described the experience as a psychological trial for which his training had not prepared him.

"About four minutes in, I realized I had no idea how many active calories I had burned, which meant I had no way of knowing if the run was actually happening," Vance said. "I looked down at my wrist, but there was only bare skin. I was forced to look at a bush. I started thinking about a conversation I had with my cousin in 2018. It was deeply unsettling."

The trend has grown so rapidly that major athletic brands are scrambling to address the phenomenon. One prominent smartwatch manufacturer recently announced an emergency software update featuring "Ghost Mode," which mimics a dead battery screen while secretly recording GPS and heart-rate data in the background to prevent users from experiencing metric withdrawal. Meanwhile, boutique fitness recovery lounges are beginning to offer "re-entry therapy" for runners who completed outdoor loops without knowing their exact training load.

Athletic trainers suggest that those insisting on participating in the trend should take strict safety precautions to avoid mental fatigue.

"We do not recommend going cold turkey," said Sarah Jenkins, a certified running coach who now specializes in digital-detox athletic training. "If you must run unmonitored, start by leaving only one earbud at home, or perhaps wear your smartwatch but tape a small piece of cardboard over the screen. You need to transition slowly back into the physical world."

The national advisory recommends that anyone attempting to run without a device should carry a laminated card containing their emergency contact information, their home address, and a brief, written explanation of why they decided to leave the house in the first place.
