I run for the journey, not the PR (Personal Record). As a proud back-of-the-pack runner, I’ve discovered that running is about so much more than speed — it’s adventure, sanity, connection with incredible people, and hopefully a ticket to long-term health, both physical and mental. I’m here to enjoy the ride, and the conversations along the way.
These stories take you from my daily Central Park “mind laundry” sessions to 155-mile self-supported ultramarathons across some of the world’s most unforgiving terrain. The ultra entries were written each night after 26+ miles of desert running, when exhaustion met exhilaration and my thoughts flowed onto paper in ways that surprised even me. Some editing for clarity, but the raw honesty remains.
My most recent escapades ran me right into a wall called sobriety which rang its bell on November 1, 2024, 1 day after my 54th birthday. I am learning daily how to embrace my new mantra of sober minded living and in return have found that the spectrum of colors in my life has gone full tilt. My world has expanded well beyond what I thought was possible and I am excited to share and hopefully inspire others with words, ideas and connection.
