Training load and Tempo runs are talked about like crazy, but without real data shared as a whole it’s just hot air. If you are interested in Tempo training a good read of sample pages of the Kinetic Manual are a must, not crappy videos on research high lights without evidence of athletes training. You must show the data and all of the data to have context and applied science. Yes I in the past I talked about energy systems loosely, but I admit I was wrong about communicating this information. Now it’s about show and not tell. Great you can read research, but I have learned the hard way that visiting other coaches is needed to get the big picture. Take a look at some of the example pages of the Kinetics Manual to get an idea of being rooted in reality.
