How we measure

Every number comes from map data, worked out in code.

Our numbers come from OpenStreetMap, the free and open world map. A program measures them; nobody types them in, and hotels can't pay for a listing or a higher spot.

How close are the times?

We tested both methods against real routes, with the method and the pass mark written down before the test ran (November 2026). Driving passed: on 80 hotel and venue pairs, half our times were within 2 minutes of the routing service and 88% within 5; ours run slightly long, so you're rarely late. Walking failed: a straight line can't see a river, a highway or a rail line, and youth complexes often sit right behind one (a hotel that looked 18 minutes away was an 88-minute walk). So we no longer estimate walks at all: every walk time on this site comes from a real walking route.

The map refreshes every month. See a mistake? Send a correction, and if you like, fix it on OpenStreetMap as well, so every map gets better.
