Looking at the summary stats September turned out a pretty good month for my running.
Looking at the fitness vs fatigue graph section corresponding to september, the line stayed pretty constant, showing I kept my training level pretty constant. Later in the month I pushed a bit more as the peak in fatigue shows.
In the bottom graph, the thicker black line shows the best speed achieved for given distances in september. I achieved my best speed of the year for all distance between 6km and 13km. You can see that as the thicker black line for september is the minimum for the year, and I did quite significantly better in speed than august.
Meanwhile the best heart rate profile shows that this was achieved without pushing the heart rate more than the other months. Actually, the september line (black thick line) stays quite below the max of the year for any duration. This is pretty satisfying: better speed without pushing much more…
