Josh Rosenthal is the founder of Borderlands, an editorial media company built around trail running, ultrarunning, and the culture surrounding the sport. Through essays, films, interviews, and the Borderlands Trail + Ultra Running Podcast, he is building Borderlands into a media institution for deeper stories, sharper counterpoints, and a fuller celebration of trail running.
His work brings taste, curiosity, and cultural analysis to a sport often covered through race results, gear, and athlete-led narratives.
