Endurance Innovation examines the technology, science, and engineering shaping modern endurance sport. Each episode features a focused conversation with researchers, coaches, and industry practitioners working in areas such as cycling aerodynamics, triathlon equipment, performance modeling, training science, biomechanics, and data analysis.

Rather than speculation or trend-driven commentary, the show emphasizes evidence-based methods and practical applications for athletes and coaches across cycling, triathlon, and other long-course disciplines. Topics include aerodynamic testing, cooling, running and cycling performance, endurance nutrition, training strategies, and the tools that support both high-performance and age-group athletes.

New episodes are released periodically.
