About

At Arnald Performance, we believe running has the power to improve more than race results. It builds confidence, resilience, and a healthier, more balanced life. Our coaching is built around three simple principles:

Plan. Partnership. Progress.

Every athlete receives a personalized training plan, ongoing coaching, and the accountability to stay consistent - even when work, family, and life get busy. Because lasting progress isn't built through perfect weeks; it's built through consistently showing up over time.

Founder Scott Arnald is a Waterloo native with nearly 30 years of competitive running and coaching experience, combined with 16 years of leadership in the corporate world. As a busy professional and father, he understands firsthand how challenging it can be to prioritize health while balancing career, family, and everyday responsibilities.

Scott competed as a five-year varsity athlete at the University of Waterloo in both Cross Country and Track & Field, earning seven OUA medals, four U SPORTS (formerly CIS) medals, and three All-Canadian honours and represented Canada international at the World University Cross Country Championships.

His own running journey has included performances from the 1500m (3:45) to the marathon (2:33 at the Boston Marathon), but his coaching philosophy isn't built around elite performances - it's built around helping individuals achieve goals they once thought were out of reach.

Whether you're training for your first 5K, chasing a marathon personal best, or simply looking to build a healthier, more active lifestyle, Scott's coaching provides the plan, partnership, and accountability to help you make lasting progress.

“Running changed my life. My mission is to help busy professionals experience the same confidence, resilience, and lifelong health that running has given me.” Scott Arnald
