What does it really take to endure when the air thins, the quads burn, and doubt gets loud? We sit down with ultrarunner Katharina Hartmuth—Hardrock and UTMB podium finisher and winner of the 330 km Tor des Géants—to unpack the mental game of mountain ultras and the deeper work that fuels lasting resilience. From long stretches above 12,000 feet to the rare quiet of a small, devoted race community, Katharina explains why Hardrock feels both brutal and beautiful—and why she keeps coming back.

Katharina is candid about the lows: altitude-driven vision issues, bonks that won’t quit, and the storm-lashed nights where every step is a question. Her toolkit blends practical strategy and inner steadiness—separating pain from harm, checking ego at the door, and letting joy lead and metrics follow. We go further into healing, where she draws a firm line: running is therapeutic, but it isn’t therapy. Years of psychotherapy widened her window of tolerance, rebuilt trust, and turned setbacks into learning. We explore stigma, access, and the biology of stress, showing why mental health care deserves the same respect as injury rehab.

Injuries have tested her in recent years: a car accident, knee surgery, a last-minute bone bruise, and a nagging foot issue. Instead of spiraling, Katharina has learned to reframe recovery as training for patience, leaned on cross-training and strength, and practiced self-kindness that maintains her sense of worth and identity. She also shares how she’s reshaping life for sustainability—creating more rest, more nature, and taking a bold step to focus on running full-time.
