Chris Napier quite literally wrote the book on the Science of Running. He is a professor of Physical Therapy at the University of British Columbia in Vancouver as well as a practicing physiotherapist, 2:33 marathoner, and medal winner at the Canadian Track & Field Championships in 1996 and 1997. Chris earned his diploma in Sport Physiotherapy and has a PhD in Running Biomechanics and Injury Prevention. With his academic background, Chis shares his knowledge on what the research has proven out and what we've learned from experience. In this conversation, we talk about: Who should modify their cadence and when Why foot strikes are better left alone Benefits of logging more than your running stats We also cover the myths that never die: Running is bad for your knees Static stretching prevents injuries Endurance runners should lift for endurance  Certain types of shoes can help you prevent injuries Chris is passionate about educating runners to make wise decisions in their training and recovery.

It’s heating up where I am and I’m ending my runs a lot sweatier than I was just a month ago. I know I’ll be paying a lot more attention to my hydration and electrolyte needs.
