400 Meter Workout
This workout is for mid distance sprinters who desire to run the 400 of their life. Anyone who has run the 400 knows that this race is the ultimate in strength, power, speed-endurance, and flat out guts. Breaking 50 seconds has always been the gold standard while running it below 45 seconds puts you in an elite classification. I only wish I came across this workout 20 years ago. http://speedendurance.com/2008/07/29/400-meter-training-2-x-300m-or-2x40-second-workout/
This workout is meant for those high school, college, and masters runners who still love the thrill that only the 400 can deliver and find themselves dreaming of this race years after they have competed in it. Myself included.
