I work with amateur endurance athletes, which mostly means people with full-time jobs training for something that frightens them slightly. The common problem is under-fuelling. People train hard, eat like someone who does not train, and then wonder why the sessions feel heavy and the sleep is poor. Fixing intake usually does more than any change to the training plan. I cover daily intake, fuelling around sessions, race-day strategy, and the gut training that stops race nutrition going wrong at kilometre thirty. Evidence-led, no supplements sold, and I will tell you plainly which of the things you have read are not supported.
