Load & form

Fitness, fatigue, and whether today is the day.

Load per session, chronic and acute load across the season, and the balance between them — so a taper is something you can see arriving rather than something you hope you timed.

Form, in one number

Chronic load is fitness, acute load is fatigue, and the gap between them is form. Fresh, building or overreaching — with the thresholds for each spelled out rather than left to folklore.

The week you actually did

Daily load with the session behind each bar, and the week’s totals for time, distance, load and session count. Enough to spot the spike that becomes next week’s three flat days.

Where the shape changed

Best efforts across durations, this block against the last one and against all time. Improvement is the part of the web that grew; a block that only produced fatigue shows up as one that did not.

Load computed from real thresholds

Load is scored against a measured LT2 rather than an estimated FTP, so the same 200-point week means the same thing in March and in August — and the same thing for two different athletes.
