Daily training stress → fitness, fatigue and form · 16 weeks
Season readiness: 111 days from Mar 4 to Jun 22. Fitness ends at 60.6, fatigue at 46.2, form at +14.2 — fresh — race window. 2 events marked: Tune-up crit on Apr 26 (form -9); Alpine Gran Fondo on Jun 22 (form +14.2). Fitness is a slow and fatigue a fast exponential average of the same daily load; form is yesterday's fitness minus yesterday's fatigue, so it shows the freshness each day starts with.
Point at the chart, or tab into it and use the arrow keys · Page Up / Page Down jump between race days.
Feed notes: 31 missing days treated as rest (0 load) so the averages decay through them.
