This post highlights a way I approach coaching busy triathletes, including Ironman racers. This “minimum effective dose” approach was the foundation of my 10 hours per week Ironman training experiment. However, it’s a good way for ANY triathlete to think about their training.
Most triathletes, especially Ironman racers, (as well as some coaches) think of training primarily in terms of overload and adaptation. In other words, they pile on as much training as they think they can handle or whatever they think it takes to achieve their goals. They feel the more they can pile on without injury, the more their body will adapt and get stronger.
