PacecraftAI builds your plan around you as you actually are — current fitness, available days per week, target race date — and adjusts the schedule every week based on how your training is going. Miss a long run on Saturday? The AI reshuffles the week. Run exceptionally well for two weeks in a row? It moves your progression forward.
