"My mission is simple:help aspirational men unlock their mental and physical potential by embracing challenge, mastering discipline, and turning up every single day, no matter how tough it gets."
Early Life:Resilience Forged Through Adversity
Born as an illegitimate, concealed birth, Marc’s early life was defined by hardship. Left outside a hospital in a cardboard box and raised in a farming family in rural Lincolnshire, he grew up in an environment that demanded hard work and resilience. Despite this, Marc often felt like an outsider, longing for a life beyond the confines of his rural upbringing.
Rugby offered Marc his first taste of discipline, teamwork, and camaraderie, shaping his understanding of leadership and grit. These qualities carried him into university and later fueled his pursuit of a long-held dream: joining the British Army’s elite Airborne Forces. However, a medical discharge from an injury sustained during training abruptly ended his military aspirations. This devastating setback forced Marc to confront his identity and chart a new path forward, ultimately laying the foundation for his coaching philosophy.
The Road to Uncharted Performance
Marc’s passion for hard training, systems thinking, and helping others became the cornerstone of his career in fitness. Initially, he began as a strength and conditioning coach, working with a diverse range of clients, including athletes in high-performance environments. Over time, Marc realized that true transformation required more than physical training—it demanded mental resilience and emotional growth.
To deepen his expertise, Marc immersed himself in the study of neuropsychology, cognitive behavioral therapy (CBT), neurolinguistic programming (NLP), and flow science. These disciplines became integral to his coaching practice, enabling him to address both the physical and mental barriers that hold people back.
In founding Uncharted Performance, Marc created a platform designed to guide men toward becoming their best selves—not just in the gym, but in life.

"For me, these experiences are about more than the physical challenge. They’re about being fully present, connecting with others, and discovering new levels of resilience."
Coaching Philosophy
Marc’s coaching is built around four core principles:
Honesty
Encouraging clients to confront their truths, free from excuses or self-deception.
Resilience
Teaching that hardship is an opportunity to grow, not a reason to quit.
Integrity
Doing the right thing consistently, even when no one is watching.
Consistency
Emphasising small, daily actions that compound into long-term success.
His approach focuses on raising not just the ceiling of what clients can achieve but also the floor of their daily performance. By eliminating wild oscillations in motivation and output, Marc helps his clients build a foundation of habits and behaviors that create sustainable growth.
