Part 5/8:
To ensure I maintain this upward trajectory of running fitness, I turned to a concept I've discussed previously: training load. This measure encompasses both intensity and duration of workouts, providing insight into the physical stress placed on my body during training.
Within Coros Evol Lab, the metric of base fitness is visually represented as a 42-day rolling average of training load. To effectively raise my base fitness, I need to maintain a training load exceeding 75 with each run. However, caution must also be exercised; if I excessively spike my training load, I run the risk of injury.
