The problem with most training plans is that they don't focus on the one thing you need to become a better runner .... your engine!
If you've been running for any length of time you'll know that how efficient you are at burning energy is what determines your performance.
If you are inefficient you will splutter along never really getting out of first gear...
.. but if you improve your efficiency all of a sudden you will be flying along like a finely tuned race car.
