Coverage analysis
What 45 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 45 minutes by bike, the Austin cycling isochrone captures the recreational cycling range — a recreational and extended-commute footprint where destination concepts draw committed cyclists from a wide area. 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 45 minutes cycling: ≈ 70–130 km². Common applications for this zone include trail-head retail siting, outdoor gear shop catchment analysis, cargo-bike delivery radius planning, cycling event venue selection.
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.
