I totally agree, and I think this is what has happened with a number of British sprinters that were successfull at the junior level. Especially Malcom Lewis Francis. When he was a junior - he was the fastest junior in the world for two years, and he was only training three days a weak. In the summer, one of those days was sometimes just a competition day plus two training days. Then when he started to compete against the seniors he got beaten and I don’t hink his coach handled that so well. No I can happily train 6 days a weak (sometimes 7) because of the nature of my training, and cause I am used to it. But I think Malcom Lewis Francis probably ramped up his training, too much too soon, at high intensity level, and probably started doing 5 or 6 days a weak. Christian Malcom is another sprinter that was better as a junior than a senior.
