Health Dashboard

Every run here has its first 5 minutes excluded (heart rate lags actual effort at the start) and likely sensor dropouts or stale readings across data gaps filtered out; runs without enough clean data are left out entirely rather than shown as an unreliable average.

Pace by heart-rate zone

Average pace at each HR zone, by period — every 15-second sample from every run is tagged by the zone your heart rate was actually in at that moment, so a run's warmup/tempo/cooldown segments each count toward their own zone instead of averaging into one misleading number. A period/zone combination with under 5 minutes of data is left out of the trend rather than shown as an unreliable average.

Table

Same-route comparison

Runs that start in the same place and cover the same distance are almost certainly the same physical loop, so pace differences here reflect fitness rather than a harder or hillier course. Only routes run at least 7 times are shown; pick a route to see its own runs at a scale that isn't squished by the others.

Miles per period

Total running mileage per month, except Past Month, which shows one bar per week.

Runs per period

Number of runs per month, except Past Month, which shows one bar per week.

Efficiency Factor

Speed ÷ average heart rate per run (×100) — a standard way to trend aerobic fitness that isolates how efficiently you're running at whatever effort a given run happened to be, instead of comparing pace only within whichever zone that effort landed in. Higher is more efficient.

Predicted pace at 150 bpm

Each run's own pace-vs-heart-rate relationship, read off at a fixed reference heart rate instead of whichever zone a run happened to spend time in. Lower is faster at the same effort. Only shown for runs where heart rate varied enough within the run to fit a trend.

Efficiency Factor — easy runs only

The same Efficiency Factor as above, limited to steady/easy runs (almost no time above Zone 3) so interval workouts don't mix hard and easy effort into one trend.

Workout volume

Trailing 12 months, one cell per day — color is total minutes that day, not workout type, so a full year fits in one view. Hover a day for the breakdown.

Workout type

Same grid, colored by category instead of volume. A day with more than one category splits into horizontal bands (Cardio on top, then Strength, Racquet Sports, Mind & Recovery, Outdoor & Other — always in that order, so the same combination of types looks the same on any two days).
