Why are Relative Effort and Fitness decreasing? I’ve been training consistently for a couple of years now. Over the last few months, my Relative Efforts have decreased significantly, even though I am training at about the same level, both in terms of duration and intensity of workouts in any given week. As an example, long runs in January/February were about RE 90, whereas now in July they are RE 40-50 at a similar pace and heart rate on the same routes. At the same time, my Fitness score is steadily decreasing. From 75 in early March, it’s decreased week on week to 35 today. Again, I am training at about the same level as I always have. Last week, for example, I did hard intervals, strength & conditioning and a couple of long runs. My training is varied and no week looks exactly the same as another. In the middle of this “decline”, I got significant 5k and 10k personal bests in May/June, after achieving a half marathon best in March. Most importantly, I don’t feel as though my fitness and form is decreas
