Coverage analysis
What 45 minutes on foot covers in Denver.
Denver's grid is unusually forgiving for drive-time modeling — until you hit the foothills west of I-25, where isochrones collapse against the Front Range and reachable area falls off a cliff. The metro's spoke-and-wheel highway system (I-25, I-70, C-470, E-470) produces dramatically asymmetric trade areas.
At 45 minutes on foot, the Denver walk-time isochrone captures the urban mobility boundary — a wider pedestrian catchment used for destination walking, accessibility auditing, and urban mobility analysis. Unlike a simple ≈ 3.5 km radius circle, the real pedestrian-network polygon follows Denver's actual street grid, accounts for crossings, parks, and dedicated walk paths, and contracts sharply around freeways, rail corridors, and waterways that break pedestrian continuity.
Walk-shed area at 45 minutes: ≈ 7–15 km². The 45-minute isochrone is the standard input for urban accessibility auditing and transit-gap identification.
The city-level population of 716,577 and a median household income of $78,177 give a sense of Denver's density, but the figure that matters for walkable-retail siting is the population inside the pedestrian polygon — not the city as a whole. That number shifts dramatically depending on whether you're anchored in a high-density urban core or a lower-density neighbourhood where blocks are long and crossings are scarce. Use the tool above to set your actual candidate address, then generate the isochrone to see the real walk shed.
