The Connected Endurance Athlete

Triathlon does not have a shortage of measurement. It has a shortage of coordination. Three disciplines, a gym, recovery, fuelling, equipment, environment and the rest of an athlete's life have to be reconciled into one week, and no product on the market holds all of it in a form a coach can reason about. This paper argues that the honest opportunity in endurance sport is reconciliation and explanation rather than prescription. A system earns its place by holding the whole week in one record, naming what it cannot see, stating the error on the numbers it reports and helping a coach and an athlete make a trade-off they can both defend. It argues equally firmly that composite readiness scores, automatic plan rewriting and any inference about energy availability belong outside the product.
