Meet Erinne Guthrie

Head Coach, Founder & Chief Motivation Officer

Coach Erinne Guthrie specializes in optimizing the performance and well-being of triathletes, blending triathlon-specific training with holistic lifestyle principles to deliver proven, lasting results. Since founding Full Circle Coaching in 2009, she has guided thousands of athletes to cross their dream finish lines with strength, confidence, and balance.

With over 27 years of racing experience—including more than 360 triathlons and countless podium finishes—Erinne brings unmatched expertise to her athletes. She is a USA Triathlon Level II Certified Coach, CHEK Holistic Lifestyle Coach (Level III), USMS Masters Swim Coach, Metabolic Efficiency Specialist, and USA Cycling Federation Coach, among other credentials. Her programs integrate smart training, nutrition, mindset, and recovery strategies to ensure her athletes not only perform at their best but also sustain their love of the sport.

But Erinne’s philosophy comes from more than professional accolades—it’s deeply personal. Early in her triathlon journey, her obsession with training cost her a marriage. That experience shaped her mission: to help athletes chase their biggest goals without sacrificing their health, happiness, or relationships. She is committed to showing that you can thrive in triathlon and in life when training is balanced, intentional, and holistic.

Beyond coaching, Erinne is a passionate contributor to the triathlon community. She has led free clinics, spoken at USAT coaching seminars, and inspired athletes of all abilities by racing alongside physically challenged athletes and children. In 2022, she raised over $128,000 for 4KIDS by cycling 3,000 miles in 7 days as part of a four-person team. She also races with Team Thumbs Up International and continues to take on new challenges as an athlete herself.

A native Floridian with a profound love for the ocean, Erinne enjoys surfing and free diving in the Bahamas and Hawaii, often alongside her daughter and sisters. With a mantra of daily service to the world, she views triathlon not only as a sport but also as a platform for building resilience, community, and a positive impact on others.
