# About City on Foot

Small, honest tools for people who like to see a city at walking pace.

## What it is

City on Foot answers the everyday questions of walking: how long it will take, how far your steps went, what pace you walked, roughly what energy it used, how a day of sightseeing fits together, what a recorded route looks like, and how much daylight you have. It is free, needs no account and shows no ads.

## How it works

Every calculation runs as JavaScript in the page you are reading. Nothing you type, and no GPX file you open, is sent to a server. Once a page has loaded it keeps working offline, which is handy on patchy mobile data.

## Where the numbers come from

- Walking speeds: published research on normal adult walking speed (Bohannon and Williams Andrews, *Physiotherapy*, 2011), with 4, 5 and 6 km/h presets.
- Hills on the walking time calculator: Naismith's rule (1892), one minute per 10 metres of climb.
- Step length: the common pedometer rule of thumb of 41.3% (women) or 41.5% (men) of height.
- Calories: MET values from the 2024 Adult Compendium of Physical Activities.
- Sunrise and sunset: the NOAA solar position algorithm, checked against the US Naval Observatory.
- GPX distances: the haversine formula on a sphere of the Earth's mean radius.

Each tool page explains its method under “How this is worked out”. All results are estimates: people, pavements and weather vary.

## Contact and feedback

There is no account system and no contact form. The site is a set of static pages; the [privacy page](https://cityonfoot.me/privacy/) says exactly what the server sees.
