Intensity Metric Triangulation (a.k.a. "How to better understand the effectiveness of your workouts")
Our friends Will and Jason at Tri-Hard Coaching are some of the most experienced and science and research driven coaches available. Working with athletes of all levels, Tri-Hard has some helpful presentations posted on their site that can help you get more out of your workouts and training. This “Intensity Metric Triangulation” slideshow/presentation describes how to integrate pace/power, heart rate and perceived exertion to better understand how workouts/races are going, and how to adjust based on your response to exercise.
Train smarter and don’t hesitate to ask Will and Jason questions as they are happy to help and are quite qualified.
