Trail running fuels my passion for the outdoors and builds the endurance, agility, and mental toughness essential for any challenge. Functional strength training is an ingrained habit that ensures my body is strong, stable, and resilient. Together, these disciplines prepare me for the unique demands of Spartan obstacle course racing, where endurance, strength, and adaptability are all put to the test. This approach is the foundation of my success, giving me the determination and resilience to take on tough challenges whether I'm outdoors or in the office.
