Coach Calum Neff began running at the age of four years old and over the past 30+ years has trained and studied under coaches and running programs all over the world. Always an athlete that asked "why?" and constantly reading training material from a young age through to today, led to a natural progression and passion for coaching. Over the past 15+ years Neff has coached every level of athlete from elementary school, high school, collegiate, and adult, introductory-to-elite, for every distance from 100 meter to 100 mile. As a self-coached runner Neff competes world-wide at an elite level.

The international experience, personal experimentation, and understanding of multiple approaches brings a unique perspective that continues to adapt and improve each day. This allows for smart, efficient, customization, and applicable training for any athlete.
