Coverage analysis
What 15 minutes cycling covers in Austin.
Austin's drive-time map is shaped by the Colorado River, a single congested loop highway (MoPac/I-35), and explosive northward sprawl into Williamson County. A 15-minute radius from downtown looks tiny on paper but routinely fails to capture the actual catchment because of bridge bottlenecks.
At 15 minutes by bike, the Austin cycling isochrone captures the neighbourhood cycling zone — the area where cyclists make routine, repeat trips without deliberate trip planning. Unlike a flat radius circle, the real cycling-network polygon follows Austin's actual bike lanes, greenways, and low-traffic streets — reaching further along protected corridors while contracting where motorways, rail yards, and rivers lack cycle crossings.
Coverage area at 15 minutes cycling: ≈ 8–15 km². Common applications for this zone include urban fitness and specialty grocery site selection, food-hall trade area analysis, cycling infrastructure planning.
The city-level population of 974,447 and a median household income of $86,556 give a sense of Austin's economic density, but the figure that matters for cycling catchment analysis is the population inside the polygon — not the city as a whole. That number shifts significantly depending on whether your origin is in a dense urban core or a lower-density suburban corridor. Use the tool above to set your actual candidate location, then generate the isochrone to see the real cycling catchment.
