A Science-Based Approach to Peak Performance
With decades of experience and teachings from some of the world's top coaches, I use cutting-edge technology to optimize biomechanics, efficiency, and performance. AI-powered run form analysis from Movaia provides detailed movement insights to help you run faster and reduce injury risk. Every training plan is meticulously structured in Final Surge, an industry-leading platform for scheduling, tracking, and analyzing performance data. These tools, combined with my expertise and personalized approach, ensure you receive the most effective, science-backed coaching available.
When I transitioned to marathons in my late 30s, I learned firsthand what it takes to break through plateaus and set new personal bests. Now, with 17 marathons behind me—including all six World Marathon Majors—I continue to compete at a high level, most recently securing 2nd place overall at the 2024 Mississauga Marathon. I know what it takes to train efficiently and maximize every workout, and I’m here to help you do the same.
