Health

Built from my own data, end to end

The data

Workouts from Garmin; daily metrics from my Garmin watch, all through Intervals.icu. The page reads its API on the server and refreshes at most once an hour. Nothing is typed in or downloaded by hand.

Only real numbers

Every figure is computed from the data. Days without a reading stay blank, nothing is estimated except where a section says so, and the animations only ever travel up to the real value.

Privacy

No GPS tracks, places, start times, activity names, notes or body weight reach the page. Workouts synced through Strava are left out, as Strava's terms ask.

The Wrapped

A story you scroll: each step's visual follows the scroll. Runs, walks and rides follow real OpenStreetMap routes, worked out once and stored, so the live page never calls a router. Swims are open-water crossings. Coastlines and borders come from Natural Earth.

Biological age

My fitness age from Garmin's VO₂ max estimate, read against the HUNT3 Fitness Study (NTNU, Norway). It measures aerobic fitness, not health.

Design

Ink and greys, with one accent for each kind of data, and one splash of colour for the Wrapped. Each figure appears once. Things move only as they come into view, and not at all with reduced motion.
