How this running estimate works
Σ (region population × participation × local-hour probability)
The model applies 8% broad participation to the eligible population, uses a typical 39-minute activity window, and distributes the result around local morning and evening exercise periods across population-weighted time zones.
What the number means
Outdoor and treadmill running. Transport access, weather, infrastructure, work schedules and season can shift the real total. The number is a broad modelled estimate, not direct tracking of individuals.
This estimate is for curiosity and perspective. Activities can overlap, and the totals should not be added together as if every category were exclusive.
Baseline sources
These sources anchor the normal model. Activity-specific participation and duration remain clearly labelled modelling assumptions.
Status: Activity-specific source review in progress. Last reviewed: August 2026.
