Metres covered per heartbeat (distance ÷ total beats) — the combined pace-and-HR signal. Rising means you go faster for the same effort; this is the single best "am I getting fitter" line on the page.
Share of weekly running time that was easy vs. moderate vs. hard, from time-in-HR-zone. Endurance gains come from keeping ~80% easy; the dashed line marks the 80% easy target.
Acute:chronic workload ratio (this week's load ÷ your 4-week average) against HRV. The shaded 0.8–1.3 band is the "sweet spot"; spikes above ~1.5 raise injury risk. If HRV falls as load climbs, you're not absorbing the training.
Weekly average HR while running, from Strava; a lower average at the same effort means the aerobic engine is improving
Weekly average pace; the sub-4:00 marathon pace is shown as an aspirational reference (faster is higher)
Weekly averages from Oura; rising sleep / falling resting HR signal good adaptation
Kilometres per week; the periodised plan is kept as a loose reference, not a target
Longest single run each week
Every week — volume, intensity split, efficiency and load ratio
