Susanne McArthur
Founder and Head CoachSusanne brings a lifetime of high-performance endurance sport experience to athlete development and coaching. Her athletic journey began in swimming and water polo, competing at the high school and university levels at Queen’s. During her time at Queen’s, she was named a provincial All-Star for three consecutive years, served as team captain, and received the Queen’s Merit Award in her final year in recognition of her contributions to sport and her athletic excellence.
While completing her teacher education in Australia, Susanne transitioned to triathlon, discovering a lasting passion for cycling and running. Over the following decade, she competed extensively across Ontario and Quebec, earning her Professional race licence and qualifying to compete in International Triathlon Union (ITU) events. As a professional triathlete, she raced in Sprint and Olympic-distance, draft-legal competitions and received the Ottawa Sport Award in 2005 in recognition of her outstanding performances.
Having progressed to elite-level competition across swimming, cycling, and running, Susanne has spent years testing herself against high-level competition and racing across hundreds of events. Her coaching philosophy is grounded in this firsthand experience and a deep understanding of the physical, technical, and mental demands of endurance sport.
Susanne continues to train and compete in cycling, running, and cross-country skiing. She believes that athletic development extends far beyond individual performances or results. Her approach emphasizes long-term progression, resilience, and the pursuit of excellence while cultivating a sustainable, lifelong relationship with sport. For Susanne, the true measure of success is not only what athletes achieve, but also their ability to find balance, enjoy the process, and carry the rewards of their efforts throughout their lives.
It’s uncommon to find someone who raced as a pro in their 20s and is still at it… that’s longevity, durability and experience.
Susanne founded C4XC in 2022.
