It always astounds me the audacity of someone like Kelly charging for coaching. I do not believe you need to be an incredibly talented runner to be a good coach.
But you need to have had some decent training blocks under your belt, you need extra courses, a thirst to learn more about nutrition, injury, and hormones. I really wish this type of thing was regulated more. I’m sure she says 2 x strength training on all her programmes etc yet does none herself.
There are some beautifully experienced runners at clubs that will give you advice and knowledge free of charge and gladly.
