Here is Amby Burfoot’s article with a video description by Bart Yasso himself!
My running coach likes to drop this workout throughout my training program to track my progress. Do not let the simplicity of this workout fool you into a false sense of security.
Training Tips (via Christine Luff)
This is a simple yet brutal workout. If you are willing to endure the torture, you will benefit physiologically and psychologically.
Stick with it and you will be pleasantly surprised with how well you perform on race day!
Happy running and best efforts,
p.s. Do not worry about the recovery 400M pace; your effort is better spent on consistent/negative splits during your 800M repeats. (Running 101 posts)
