Stats

Over the last 28 days of the block you have done 109% of the load the plan asked for.

The shaded area is the 7-day fatigue this plan asks for, day by day. The line is what you have actually carried. Where the line sits below the area you are behind the plan; above it and you are doing more than was asked, which is its own risk.

Today your ratio is 1.07 against the 1.09 the plan expected.

Fatigue (7 days) divided by fitness (42 days), at the end of each day so it includes that day's run. Blue is the ratio had every day gone to plan, black is the one you actually ran. Below 0.8 you are losing fitness; 0.8 to 1.3 is where fitness is built; above 1.5 is the zone that precedes injuries. Long-run days spike it briefly and that is normal; what matters is that it comes back down.

Since 7 Sep you have banked 1619 of the 1262 the plan expected by now, 357 ahead. The whole block asks for 4583.

Every day's load added to the running total since week 1. The chart above shows whether this week matches the plan; this one shows whether the block as a whole does. A missed week leaves a step that does not close up on its own, and a line that rises faster than the area is the start of the too-big week the 10% rule exists to stop.

Fitness 23.9 against 20.2 expected · fatigue 29.1 against 25.2 expected.

Fitness (chronic training load) is a 42-day average of daily load: slow to build, slow to lose. Fatigue (acute training load) is a 7-day one and swings with every week. Solid lines are what you ran, dashed lines what the plan would have produced. The gap between the two solid lines is the form chart below. Fitness is the line that has to climb into February; the dashed blue line is how far the plan expects it to go.

Fitness is a 42-day average of daily load, fatigue a 7-day one, and form is the first minus the second, read as of the morning so it never includes the day's own run. Below zero you are carrying fatigue, which is how a block builds fitness: the green band is where most of it should sit, and below it is overreaching. Above zero the fatigue has cleared, and the blue band is where race morning should land. The load is Strava's relative effort, not TrainingPeaks' TSS, so form is shown as a percentage of fitness rather than against TSS thresholds. The blue line is the form the plan expected, had every day of the block gone exactly to plan; the black line is what you actually did, continued as a thin dashed projection from today. Black above blue means you are fresher than planned, usually from a missed session; below it, more tired than planned.
